Improve FAH create & delete (#6726)

* Improve FAH create & delete

1. Create now sets deployment-tool so we can track where users are
   coming from
2. Create now sets a rollout policy like the Console
3. Delete now works
4. Delete no longer makes buildId required

* Fix test breakage where labels were wrong

* Remove unused stub

* Revert unwanted changes
