Save bloom filters for premium list entries

Browse source 
This is the first step in the migration to remove the need to load all of
the premium list entries every time the cache expires (which causes slow-
downs). Once this is deployed, we can re-save all premium lists, creating
the bloom filters, and then the next step will be to read from them to
more efficiently determine if a label might be premium.
