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

See merge request gitlab-org/gitlab!20023

This change limits the number of projects displayed

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.

Validate connection section in direct upload config

Closes #38258

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).

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.
