Fix RangeError exceptions when referring to issues or merge requests outside of max database values
When using #XYZ in Markdown text, if XYZ exceeds the maximum value of a signed 32-bit integer, we get an exception when the Markdown render attempts to run `where(iids: XYZ)`. Introduce a method that will throw out out-of-bounds values.

Make sure that artifacts_file is nullified after removing artifacts
## What does this MR do?
Fixes a problem that `ExpireBuildArtifactsWorker` is executed for all previously removed artifacts.
## Why was this MR needed?
Currently the `Ci::Build::erase_artifacts!` doesn't ensure that data are saved to database.
The bang at end of this method lets you believe that it should do so.
This adds a missing `save` to this method.
## What are the relevant issue numbers?
None, yet.
## CHANGELOG
Since this is regression in feature introduce in RC4 no CHANGELOG entry is needed.

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
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.
## Does this MR meet the acceptance criteria?

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
```
What needs to be done:
- [x] Write initial implementation
- [x] Improve implementation (@ayufan)
- [x] Write tests (@ayufan)
- [x] Improve UX of the forms (cc @markpundsack) - reviewed by @markpundsack
- [x] Improve implementation of the views (cc @jschatz1) - done by @iamphill
- [x] Write .gitlab-ci.yml documentation for `environments` - done by @ayufan
- [ ] Write user documentation (@ayufan and @markpundsack)
