Petr Pchelko 8d2c674ab0 Introduce ActorStore, ActorLookup and ActorFactory.
The ActorNormalization factory methods create
UserIdentityValue from the database rows, either via
fields of a joined table, or via a row from actor table.
They assume that the actor_id exist and throw othervise.

ActorNormalization is a storage-layer service providing
access to finding and acquiring actor_id.

The UserIdentityLookup methods do not instantiate new actor
on demand, they just find an appropriate row in the actor
table and return the result.
