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.
