Detect DBReferenceError when deleting flavor

The flavor framework currently has a TODO where the logic
to ensure the flavor isn't in use should be. Implementing
this logic will be a bit complicated this late in the cycle
since many different services can depend on the flavor.

For now we can at least catch the DBReferenceError when trying
to delete the flavor and convert it into the FlavorInUse
exception.

This leaves some notes inline about how we might go about
implemented the _ensure_flavor_not_inuse function.
