Add repository setting to enable/disable health checks

New Feature:
  * Repository struct field for IsFsckEnabled (default true of course)
  * Admin Settings section on repo options page, accessible only by
    admin users

Possible Enhancements:
  * There's no way to force running health checks on all repos
    regardless of their IsFsckEnabled setting. This would be useful if
    there were an admin API or dashboard button to run fsck immediately.

Issue: #1712
