Reduce SQL query counts in IssueReferenceFilter
## What does this MR do?
This MR adds a preparation phase for reference filters that allows them to prepare/create data structures used while iterating over HTML nodes. In this particular case the preparation phase is used for issue references to greatly cut down the amount of queries executed to get projects/issues for Markdown references.
## Are there points in the code the reviewer needs to double check?
No.
## Why was this MR needed?
Rendering Markdown containing issue references would run at most two queries for every issue reference: one to get the project and one to get the issue from said project. When rendering Markdown with lots of issue references this would result in _a lot_ of queries being executed.
## What are the relevant issue numbers?
#18042
See merge request !4410
Avoid a TypeError when initializing MergeRequest JS class with no arg
## What does this MR do?
Avoid a TypeError when initializing MergeRequest JS class with no arg.
## Are there points in the code the reviewer needs to double check?
No.
## Why was this MR needed?
Without this sane default you would get the following error when you
tried to instantiate a new MergeRequest object with no argument (i.e.
`new MergeRequest();`):
TypeError: undefined is not an object (evaluating 'this.opts.action')
## What are the relevant issue numbers?
Fixes#13525.

This reduces the number of queries executed in IssueReferenceFilter by
retrieving the various projects/issues that may be referenced in batches
_before_ iterating over all the HTML nodes.
A chunk of the logic resides in AbstractReferenceFilter so it can be
re-used by other filters in the future.
Improve pipeline status in case that pipeline has no jobs
## What does this MR do?
This MR resolves problem with pipeline status when there are no build in pipeline.
This can happen when builds were skipped - for example - by using `only`/`except` keyword in `.gitlab-ci.yml`.
## What are the relevant issue numbers?
Closes#17977
See merge request !4403
This ensures that Project.find_with_namespace returns a row matching
literally as the first value, instead of returning a random value.
The ordering here is _only_ applied to Project.find_with_namespace and
_not_ Project.where_paths_in as currently there's no code that requires
Project.where_paths_in to return rows in a certain order. Since this
method also returns all rows that match there's no real harm in not
setting a specific order either. Another reason is that generating all
the "WHEN" arms for multiple values in Project.where_paths_in becomes
really messy.
On MySQL we have to use the "BINARY" operator to turn a "WHERE" into a
case-sensitive WHERE as otherwise MySQL may still end up returning rows
in an unpredictable order.

Fix permission checks in member row (backport from gitlab-org/gitlab-ee!460)
## What does this MR do?
It improves the check we use to display or not the members' access and controls in the members list.
## Are there points in the code the reviewer needs to double check?
No, I replaced an helper with just a permission check so I think it's a better solution.
## Why was this MR needed?
There were a spec failure in gitlab-org/gitlab-ee!460 because of the refactor done in the "request access" MR.
## What are the relevant issue numbers?
None.

Turn Group#owners into a has_many association
## What does this MR do?
This turns the regular method `Group#owners` into a `has_many` association.
## Are there points in the code the reviewer needs to double check?
As far as I can tell there's no way to do this without using an intermediate association, but perhaps I'm missing something. The reason an intermediate association is needed is because the supplied Proc is applied to the _final_ association (the one returning users), this means that when using a single `has_many` you can't filter out any intermediate rows (e.g. group members).
## Why was this MR needed?
This code being a regular method would prevent eager loading of the owners of a Group, turning it into a `has_many` association resolves this problem. This was discovered in !4410.
## What are the relevant issue numbers?
None.

Fair usage of Shared Runners
## What does this MR do?
Introduces a fair usage scheduler for shared runners.
It tries to assign builds to shared runner from projects that have the lowest number of builds currently running on shared runners.
**Example 1**:
```
We have following builds in queue:
build 1 for project 1
build 2 for project 1
build 3 for project 1
build 4 for project 2
build 5 for project 2
build 6 for project 3
With the new algorithm we will assign builds in following order:
- We choose build 1, because project 1 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We choose build 4, because project 2 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We choose build 6, because project 3 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We choose build 2, because project 1 as other it runs 1 build,
- We choose build 5, because project 2 runs 1 build, where project 1 runs 2 builds now,
- We choose build 3, because project 1 and runs 2 builds.
```
**Example 2**:
```
We have following builds in queue:
build 1 for project 1
build 2 for project 1
build 3 for project 1
build 4 for project 2
build 5 for project 2
build 6 for project 3
With the new algorithm we will assign builds in following order:
- We choose build 1, because project 1 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We finish build 1,
- We choose build 2, because project 1 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We choose build 4, because project 2 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We finish build 4,
- We choose build 5, because project 2 doesn't run currently any builds and has the lowest build number from projects that doesn't run builds,
- We choose build 6, because project 3 doesn't run currently any builds,
- We choose build 3, because project 1, 2 and 3 runs exactly one build now,
```
## Why was this MR needed?
Currently, we are scheduling builds using FIFO. This is catastrophic if there are projects that create a 100-300 jobs, this basically eats most of available shared runners.
## Performance
All this logic is implemented with the help of SQL queries, because this is the fastest way to process 1k-2k pending builds in queue.
It's not the fastest SQL query, because it sorts based on number of running_builds, and this forces to calculate a number of running builds for all dependent projects. However, since we have one/two shared runners that asks every few seconds for builds this should have minimal impact on DB performance.

Add environments and deployments
This MR is a continuation of https://gitlab.com/gitlab-org/gitlab-ce/issues/17009.
The current implementation is as follow:
1. We have two new tables: `environments` and `deployments`.
2. We have a new tab: `Environments` under `Pipelines` where you can see all you environments and add a new one.
3. We add a new option to `.gitlab-ci.yml` to track where we should create a deployment for environment.
4. If environment in `.gitlab-ci.yml` is specified it will create a deployment. **If environment does not exist it will be created.** (this got changed)
5. The deployment is always successful and shows the time of the action, in that case a build that presumably should do deployment. In the future we could extend deployment with statuses: success, failure. We could extend deployments with information that this is partial or full deployment.
6. User have to create environments that he will track first.
7. User can remove environments.
8. User can retry/rollback past deployment (in that case we retry past build). The new build when succeeds it will create a new deployment.
9. Currently environment have only one parameter: `name`. In the future it should have: `variables`, `credentials` and possibly `runners` and maybe other resources.
10. Currently deployment have this parameters: `sha`, `ref`, `deployable (in this case a build)`, `user (who triggered a deployment)`, `created_at`.
The `.gitlab-ci.yml`:
```
deploy to production:
stage: deploy
script: dpl travis...
environment: production
```

Resolve "Track the number of new Redis connections per transaction"
## What does this MR do?
Add a new metric counter, `new_redis_connections`, that contains the number of calls to `Redis::Client#connect` in the current transaction.
## Are there points in the code the reviewer needs to double check?
Not sure. I tested this in kind of a brute-force way:
1. Add a debugger in the monkey-patched `connect` method.
2. With metrics enabled, start the app and load a page.
3. The first Redis connection is created by `Rack::Attack` and isn't in a transaction, but still works fine.
4. The second Redis connection is within a transaction (the page load), and increments the counter.
5. If I reload the page, neither debugger is hit.
6. If I use a Redis client and do `CLIENT KILL` on my two existing clients, then reload the page, I get 3 and 4 again.
7. If I disable metrics collection, the debugger never gets hit.
## Why was this MR needed?
We may have a Redis connection leak somewhere, so adding metrics will let us track this.
## What are the relevant issue numbers?
Closes#18451.
## Screenshots (if relevant)
Hahaha nope, not relevant.
