Resolvers
Resolvers let us find actors that have been persisted in external systems, like databases or storages. One example of resolver, is the tarant-local-storage module, which let us recover actors that have been persisted in the local storage, without losing information.
Resolvers must implement the following method:
resolveActorById(id: string): Promise<Actor>
. If the actor exists in the storage, return a promise of the configured actor, if not, returns a promise with undefined.
