Speed up expanding/collapsing diff files

See merge request gitlab-org/gitlab!24655

When v-if is false, Vue calls $destroy for every single component.
Since table-cell component was basically a wrapper around
diff_line_gutter_content we can save valuable cycles by combining them

See merge request gitlab-org/gitlab!24824

Allow Container Expiration Policy to run tag cleanup

See merge request gitlab-org/gitlab!24424

When a policy runs, it uses a new worker to allow
it to run without a user.

The policy is only accessible to users with destroy image ability

Record audit event when user is blocked

See merge request gitlab-org/gitlab!24930

The existing `Users::UpdateService` is getting more complex and does not
allow capturing state changes that caused by `state_machines`. This
replacement will help to simplify logic around blocking user and make
way for new additional features (e.g. audit event).

jQuery at.js has a hard limit on how many items can be searched. Before
it executes it's search function, it limits the array size to 1000
items. We have been hitting this bug because we have more than a
thousand users or labels [0][1].

We are planning to replace at.js [2], but in order to fix this bug for
now, we have forked at.js [3] and made adjustments, so that it works for
our usecases.

Performance wise this should have no big impact, as we are rendering a
maximum of 5 results in the most cases anyway. The search on the
javascript side is rather performant.
