Fix AutoMergeProcessWorker raises an error for merged MRs

Closes #121989

Consider absence of explicit `allow_null: true` to be an offense too

Closes #38385

Retry getting the runners token if it's not available initially

Ensure the docker runner container is stopped even if there's a
problem removing it from the project

Move backtrace cleaner from Profiler into its own class

Closes #36645

See merge request gitlab-org/gitlab!22264

And CI_JOB_TOKEN cannot access them easily

We call `GitLab::Profiler.clean_backtrace` in a lot of places where we
aren't actually profiling. It makes sense to break this out into its own
class method.

This change also reduces memory usage and speeds up the backtrace
cleaner since the regexp is computed once at load time.

Refactor code involved in git workflow

See merge request gitlab-org/gitlab!22266

Expose reference path for issuables

See merge request gitlab-org/gitlab!20354

Preload project, user and group to reuse objects

Closes #39113

See merge request gitlab-org/gitlab!21853

Add section to database docs for alternative primary keys

See merge request gitlab-org/gitlab!22044

Expose issuable references in 3 options: short, relative and full.
Short and full aways display corresponding issuable reference,
while relative displays the reference depending on the context
from which it was referenced.

Refactor some methods, classes and specs in
preparation for versioned snippets.

Move items from database MR template checklist to documentation

Add some extra checkboxes to the database MR template,
e.g. ask author to add SQL and query plan to the
description.

Limit size of search query for postgresql search

See merge request gitlab-org/gitlab!22208

When using non ES search without limits, we can easily get Stack level
too deep error. To fix it we implemented terms and character limits
for the search#show action.

Add saml identity presence filtering option to members API

Closes #118475

See merge request gitlab-org/gitlab!21931

Use `with_saml_identity=true` param to filter out
members without saml identity linked. You'll
have to have access to read group saml identities
to use this filter

Speed up path generation with build artifacts

Closes #121929

Fix stack trace highlight for PHP

Closes #121714

See merge request gitlab-org/gitlab!22258

Pick a first alternative language for Sentry stack trace highlight,
when Rouge can't decide which lexer to choose.

`StackTraceHighlightDecorator` now works with PHP and Hack languages

Previously it would take seconds to render the pipeline index JSON
(/gitlab-org/gitlab/pipelines.json) in the GitLab project. Apparently,
we render over 5000 paths for `BuildArtifactEntity`, and generation of
these paths dominated the request time.

The Rails path helpers are slow because they check the namespace and
project parameters against large regular expressions, which include
`TOP_LEVEL_ROUTES` and `PROJECT_WILDCARD_ROUTES`, respectively.

We can speed this up by generating the paths directly with
strings. While this isn't ideal, this results in a 10x improvement in
speed:

```
Calculating -------------------------------------
                orig    86.000  i/100ms
                 new     1.272k i/100ms
-------------------------------------------------
                orig      1.343k (±13.8%) i/s -      6.536k
                 new     13.756k (±15.3%) i/s -     67.416k

Comparison:
                 new:    13756.3 i/s
                orig:     1343.3 i/s - 10.24x slower
```

To prevent these helper methods from breaking if the routes ever change,
we add tests to ensure that the results are the same.
