This re-implements image commenting in merge request diffs.
This feature was previously lost when the merge request
page was refactored into Vue.

With this, we create an overlay component. The overlay
component handles displaying the comment badges
and the comment form badge.
Badges are displayed based on the position attribute
sent with the discussion.

Comment forms for diff files are controlled through
a different state property. This is so we don't
tie comment forms to diff files directly creating
deep nested state. Instead we create a flat array
which holds the file hash & the X & Y position of
the comment form.

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

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

This allows us to use a kubectl binary that should be able to
connect to Kubernetes clusters v1.9 and up.

Use our own docker image for helm install pods

See merge request gitlab-org/gitlab-ce!22778

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.

Relates to https://gitlab.com/gitlab-org/gitlab-ce/issues/53213

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.
