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.
