* Update go-generate to run as a script
It was taking forever to run via the previous Makefile command. I don't
exactly know why. Perhaps because it was passing all the packages in as
multiple arguments?
Either way, this change allows it to actually run through in about 20
minutes.
* Regenerate all mocks using latest pegomock
Pegomock version v2.9.0
* Format mocks outside of regular mocks directory.
These mocks are outside of the regular directory due to an import cycle
causing us to have to have these not under a /mocks directory so they
need to be formatted since they're not excluded.
* Add back make test target
