A Realm might have more data about a user's account in the backend database. If email address information is available, the realm could look this up on the fly to verify incoming commits. Add a new hasEmailAddress() method to check individual emails and cache results inside of the IdentifiedUser object for the duration of the current request/operation scope. Also add a method to lookup as many possible email variations as possible, for reporting in error messages or GET /emails API. Change-Id: I13fec7eb00b1bd6ddcb74323ba7205ee1b2ee42f
