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.

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

Looks like there are some legacy GitLab databases that have a NOT NULL
constraint for the `created_at` and `updated` fields.

This change fixes the migration by adding a default value to those
columns and I think we always should have it in mind when inserting DB
records through raw SQL.

To reduce the number of abstract methods, use polymorphic_paths for
collection routes. Unfortunately for member routes, polymorphic_paths
does not support namespaced classes, so still continue to override
methods.

We introduced hidden_clusterable_fields in this MR but it is no longer
needed as we have gone back to nested resource routes which should
provide the params such as `project_id`.

Also add missing interface in abstract class.
