[Geo] Add logging when create a temporary repository

See merge request gitlab-org/gitlab-ee!4594

created_at and updated_at attributes are also exposed in epic API - if
we allow sorting by these attributes it also makes sense to include them
in API response.

Move ee-files-location-check to the test stage

See merge request gitlab-org/gitlab-ee!4580

Flipper already takes care of flushing cache entries when
enabling/disabling features so it should be safe to increase the TTL.
This in turn should drastically reduce the number of Flipper queries
executed.
