Enable Phabricator admin to change the owner of a herald rule

Summary:
Added a typeahead in the edit herald rule page that allows an admin or
owner to change the current owner of a rule.  If the typeahead is emptied, the
current owner will remain owner.

Test Plan:
Created a test rule.  Changed the owner.  Deleted the owner in the
typahead. Verified expected behavior.
