step for safer usage is to remove #find_by.

Optimize merge request refresh by using the database to check commit SHAs

See merge request gitlab-org/gitlab-ce!22731

Replication slots are not supported in Aurora. Attempting to check
the lag results in the message:

```
ActiveRecord::StatementInvalid: PG::FeatureNotSupported: ERROR:
Replication slots are currently not supported in Aurora : SELECT
pg_xlog_location_diff(pg_current_xlog_insert_location(),
restart_lsn)::...
```

To avoid breaking support for background migrations in Aurora, we just
disable the check if we encounter this error.

This change also now checks whether there are any replication slots
present in the primary before checking the replication lag.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/52176

This allows us to use a kubectl binary that should be able to

Previously for a given merge request, we would:

1. Create the array of commit SHAs involved in the push (A)
2. Request all merge request commits and map the SHA (B)
3. Reload the diff if there were any common commits between A and B

We can avoid additional database querying and overhead by
checking with the database whether the merge request contains any
of the commit SHAs.

Allows users to be fetched/created via the API.

This will reduce dependencies and failure points during installation. It
will also reduce security risks from untrusted dependencies being able
to effect all our users

Removes old buttons,links and tooltips and uses
the new gitlab-ui components.
