Because the Geo Event tables do a `on_delete: :cascade`, the foreign
keys in `geo_event_log` need to have an index. Otherwise the deletion
would be very slow.

EE: Move Project#rename_repo to a service class

See merge request gitlab-org/gitlab-ee!8028

This moves the logic of Project#rename_repo and all methods _only_ used
by this method into a new service class: Projects::AfterRenameService.
By moving this code into a separate service class we can more easily
refactor it, and we also get rid of some RuboCop "disable" statements
automatically.

During the refactoring of this code, I removed most of the explicit
logging using Gitlab::AppLogger. The data that was logged would not be
useful when debugging renaming issues, as it does not add any value on
top of data provided by users.

I also removed a variety of comments that either mentioned something the
code does in literal form, or contained various grammatical errors.
Instead we now resort to more clearly named methods, removing the need
for code comments.

This method was chosen based on analysis in
https://gitlab.com/gitlab-org/release/framework/issues/28. In this issue
we determined this method has seen a total of 293 lines being changed in
it. We also noticed that RuboCop determined the ABC size
(https://www.softwarerenovation.com/ABCMetric.pdf) was too great.

[QA] Move epic-related method to EE class

This model will be used to persist into database Kubernetes properties,
such as namespace, service account name and service account token.
