Modify the call to ping the database to fail gracefully if the
database has not yet been configured by the end user, such as
after a clean install. This allows /healthcheck to return a 200
with a modified status message instead of causing a PANIC.

* add config option to enable or disable log executed SQL

* rename ShowSQL to LogSQL

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.
