Geo: Always update the default branch on the secondary

Closes #9084

See merge request gitlab-org/gitlab-ee!9064

Add docs on how web terminals are secured

Closes #52681

See merge request gitlab-org/gitlab-ce!24099

Previously, we would only update the default branch on a Geo secondary
if the default branch didn't match the primary default branch. However,
the Gitaly FindDefaultBranch RPC may return an arbitrary branch if HEAD
points to an invalid branch, so we can't trust that result to be
correct.

To ensure that the default branch is always correct, we now write it out
on the Geo secondary whenever we do a sync. This incurs an additional
filesystem write, but that should be relatively minor.

Add doc for removing Geo node

See merge request gitlab-org/gitlab-ee!8868

This appears to add "Error Tracking" and remove duplicate
"quick actions" and "register" entries.

These are used by the EE-only approvers feature

This is accomplished by taking the merge request's commits that aren't
merge commits, and removing their authors from the list of eligable
approvers.

References with namespace are inserted because this is at group scope
and iids are not unique

In the previous code, we locked the project during the migration
scheduling step, which works fine for small setups, but can be
problematic in really big installations.

We now moved the logic to inside the worker, so we minimize the time a
project will be read-only. We also make sure we only do that if
reference counter is `0` (no current operation is in progress).

Skip parsing of container scanning report if feature flag is disabled.
