This moves the internal iam service from the posix backend so that we can start implementing new iam services right in the auth module. The internal iam service has same behavior as before, but now must be enabled with the --iam-dir cli option. New single user service is the default when no other iam service is selected. This just runs the gateway in single user mode with just the root account.
