distribution: remove Pusher interface, NewPusher(), and redundant V1 checks
It's only used internally, so we can refer to the implementation itself. Given
that RegistryService.LookupPushEndpoints now only returns V2 endpoints, we
no longer need to check if an endpoint is possibly V1.

Also rename some types that had "v2" in their name, now that we only support v2.
