f7662b01c2
This changes adds a new command ``baremetal`` that works mostly like the OSC ``openstack baremetal`` command but does not require OSC and defaults to no-auth. No changes in existing commands are required, the existing OSC plugins are pulled in. Change-Id: Id4895ec37bfb58eb635e5c8519f96f1bdc30c925
