Display group/project access requesters separately in admin
## What does this MR do?
It displays the access requesters in a separate list in group & project members pages.
It also harmonize the members counter UI to use `%span.badge` everywhere (in the admin & non-admin members views).
## Are there points in the code the reviewer needs to double check?
No.
## Why was this MR needed?
To not confuse access requesters with actual members.
## What are the relevant issue numbers?
Closes#18871.

Show proper image ID on registry page

Display the container registry image ID (from the config blob) instead of the first image layer ID

Ensure that group owner cannot request access to a project of their group
## What does this MR do?
It fixes two things:

Track method call times/counts as a single metric
This changes method call tracking so only a single metric is emitted regardless of the number of calls. This allows us to more accurately measure the total execution time of a method as well as the number of times a method is called. See 851e3ff7578973c2206628424eac3b951a3c656d for more details.
Method call tracking tracked calls individually meaning the end statistics may not always be accurate enough to get a good understanding of where time is spent.

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.

Allow customising of queries used for `update_column_in_batches`
This MR makes two changes to `add_column_with_default` and `update_column_in_batches`:
1. `add_column_with_default` no longer wraps the entire set of updates in a single transaction, preventing any locks from sticking around for the duration of the entire transaction
2. `update_column_in_batches` now takes a block which can be used to customise the queries. This uses Arel as messing with raw SQL strings is a total pain
In !4381 there's a need for updating existing rows/columns in a table in batches using a custom `WHERE` condition. Without the changes in this MR this would not be possible.

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.

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.

## 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
