Adds missing rabbit_userid to trove configs

- rabbit_userid was only updated in trove.conf leaving other
  trove configuration files not having this value.
- Trove service setup was broken because of this.
- Added rabbit_userid to trove-taskmanager.conf,
  trove-conductor.conf and trove-guest.conf.
