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.

Add WSGIPassAuthorization to the keystone apache template

For the OS-OAUTH1 Keystone extension to fully work under Apache,
the WSGIPassAuthorization parameter must be set to On, rather
than the default of Off. This will make functional testing of
this extension much easier.
