Internationalisation of reports directory

See merge request gitlab-org/gitlab-ce!27742

This is one of many MRs opened in order to improve the overall
internationalisation of the GitLab codebase.

i18n documentation
https://docs.gitlab.com/ee/development/i18n/externalization.html

Rails 5.1's `exec_no_cache` doesn't call `async_exec` any more, but
`exec_params`: https://github.com/rails/rails/pull/33188

This means that the DB summary in the performance bar was wrong. The
individual query details were still correct (we subscribe to
ActiveRecord events for those).

We can remove this once the upstream PR to peek-pg is in a release and
we update to use that release.

Pass excluded paths to SAST and DS

See merge request gitlab-org/gitlab-ce!28018

Propagate DS_EXCLUDED_PATHS to dependency_scanning job,
and SAST_EXCLUDED_PATHS and SAST_BANDIT_EXCLUDED_PATHS to sast job.
This makes possible to excluded certains paths from SAST reports
and Dependency Scanning reports, respectively.

Whitelist query limits for internal API

Closes gitlab-ee#11450

See merge request gitlab-org/gitlab-ce!28037

When creating a merge request for push options, there may be over 100
queries that are run to create a merge request. Even after we reduce the
number of queries by disabling the Sidekiq jobs, it appears we still
hover near this limit.

Closes https://gitlab.com/gitlab-org/gitlab-ee/issues/11450

Schedule `git pack-refs` after push

Closes #59715

See merge request gitlab-org/gitlab-ce!27826

PackRefs is not an expensive gitaly call - we want to
call it more often (than as part of full `gc`) because
it helps to keep number of refs files small - too many
refs file may be a problem for deployments with
slow storage.

Upgrade Gitaly to 1.40.0

See merge request gitlab-org/gitlab-ce!27968

Includes catfile cache, as well as fixes to the catfile cache code that
caused it to panic in Gitaly

Update rebasing to use the new two-phase Gitaly Rebase RPC

Closes gitlab-ee#5966

See merge request gitlab-org/gitlab-ce!27446

The new two-step Gitaly `Rebase` RPC yields the rebase commit SHA to the
client before proceeding with the rebase.

This avoids an issue where the rebase commit SHA was returned when the
RPC had fully completed, and in some cases this would be after the Rails
`post_receive` worker services had already run. In these situations,
the merge request did not yet have its rebase_commit_sha attribute set
introducing the possibility for bugs (such as previous approvals being
reset).
