Fix failure in squash_merge_request_spec by reloading page if commit does not appear

Preload group ancestor to avoid N+1

See merge request gitlab-org/gitlab!20977

When checking permissions for a group, it always tries to load
group ancestor (to check SSO). If we check permissions for related
groups (for which we are sure that all of them have same root), we
just preset this root group before checking permission.

Fix order-dependent spec in Gitaly cleanup spec

Closes #38535

See merge request gitlab-org/gitlab!21370

Stubs for Gitaly calls are memoized by storage and service names in the
`@stubs` class variable. Normally this doesn't cause a problem, but an
example in `spec/lib/gitlab/gitaly_client/cleanup_service_spec.rb`
expected that a new stub would always be instantiated. Since
`spec/services/projects/cleanup_service_spec.rb` preceded
`spec/lib/gitlab/gitaly_client/cleanup_service_spec.rb`, the stub had
already been instantiated, causing the test to fail.

To fix this problem, we just clear out the Gitaly stubs for
`spec/lib/gitlab/gitaly_client/cleanup_service_spec.rb`.

Resolve "Gitaly N+1 queries in /api/:version/groups/:id"

Closes #31031

See merge request gitlab-org/gitlab!20023

This change limits the number of projects displayed
in GET /groups/:id API, to prevent N+1 in Gitaly

Preload job_artifacts when loading builds in stage

Closes #38306

See merge request gitlab-org/gitlab!21307

The test appears to be failing occasionally because the diff notes
aren't always visible within the browser when the diff view is
reloaded. We fix this by clicking on the "Jump to first unresolved
thread" button to ensure the notes are shown.

Closes https://gitlab.com/gitlab-org/gitlab/issues/38277

Validate connection section in direct upload config

Add missing spec for fogbugz importer

See merge request gitlab-org/gitlab!20981

For some reason, `Settingslogic` doesn't always provide the right error
message when the `connection` block is omitted. Sometimes it erroneously
attributes the error section to a different part of the YAML
(e.g. `backup`, `dependency_proxy`).

This commit adds on more information on which `connection` block is
missing from the `gitlab.yml` (e.g. LFS, artifacts, or uploads).

and their status.

Add security configuration navigation item

See merge request gitlab-org/gitlab!20711

This commit adds a new navigation item to the main navigation. It
sits within a project's "Security & Compliance" submenu and
links to the security configuration screen.

These files were updated automatically with this script:

```
result="$(awk '/[{\[]$/ { printf("%s\t", $0); next } 1' $1)"
echo "$result" > $1
yarn prettier --write $1
```

Includes related import reordering for IDE-related
files to fix eslint warnings.

See issue https://gitlab.com/gitlab-org/gitlab/issues/29243
which tracks the overall effort for migration to Jest.

Running any Rake task would show:

ARNING: Sidekiq testing API enabled, but this is not the test
environment.  Your jobs will not go to Redis.

To fix this, we move the `require` statement into the import task.
Now this message only shows when running the import job.
