Ensure Todos counters doesn't count Todos for projects pending delete

Use `TodosFinder` instead of `current_user.todos` to filter projects
pending delete on Todos counters helpers.

Counters should not reflect the number of Todos displayed on the tabs.

Fixes #18633

See merge request !4663

Disable the unlink feature for SAML connected accounts (social login).

This disables the ability to manually unlink your SAML account, if you have one connected. In certain scenarios, the only allowed login mechanism can be SAML, and if you unlink your account you will be locked out of the system (configuration dependent).

Fixes #18613

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.

## What does this MR do?
Adds a better validation for only and except which can contain regexps.

## Why was this MR needed?
Currently the RegexpError can be raised when processing next stage which leads to 500 in different places of code base.
This adds early check that regexps used in only and except are valid.

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?

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.

```

## Specific runners

It doesn't affect the specific runners which still serve builds FIFO.

See merge request !4634

Shows build scroll buttons after build is complete

## What does this MR do?

Shows the build scroll buttons whenever there is a build trace. Previously they were only shown when the build was active.

## What are the relevant issue numbers?

Closes #18515 

## Screenshots (if relevant)
