Show lease on Repository Operation detail view and awaken on failures

Summary:
Ref T182. Couple of minor improvements here:

  - Show the Drydock lease when viewing a Repository Operation detail screen. This just makes it easier to jump around between relevant objects.
  - When tasks are waiting for a lease, awaken them when it breaks or is released, not just when it is acquired. This makes the queue move forward faster when errors occur.

Test Plan:
  - Viewed a repository operation and saw a link to the lease.
  - Did a bad land (intentional merge problem) and got an error in about ~3 seconds instead of ~17.
