Geo - Respect the next retry time when re-verifying failed repositories

Closes #8643

See merge request gitlab-org/gitlab-ee!8661

Fix deprecation: Passing a class as a value in an Active Record query is deprecated

Scope the queries to retrieve failed repository verifications
by (repository|wiki)_retry_at < Time.now to respect the next

(repository|wiki)_retry_at.

Fix deprecation: Passing a class as a value in an Active Record query is deprecated and will be removed.
