Drop unnecessary created_at columns in Geo event log

It looks like the event_log table already has a created_at entry, while the specific event logs (e.g. repository_deleted_event) contain a redundant entry.

created branch 3176-drop-unnecessary-created_at-columns-in-geo-event-log

assigned to @dbalexandre

added database label

Do we keep the timestamps in the specific events, or in the parent log entry?

My vote would be for the latter.

@dbalexandre can you unassign yourself if you're not working on this?

@nick.thomas this is already done, see https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/2714
