[keycloak-dev] evict on update/remove, make providers cache aware

[Bill Burke]

I was thinking that we change all Mongo and JPA adapters, and 
RealmProvider and UserProvider methods that can update or remove models 
from the database and have them evict the cache of that type.  This will 
make sure that if somebody gets a non-cached model or provider and 
performs an update, the cache is still invalidated.  Sound ok?

Thanks,

Bill
