Rename 13_role to full_ha

13 role was a pretty bad name b/c it never had
13 separate roles.

Add rebuild command

The rebuild command can be used for debugging, as it will build
only the nodes that do not exist for a test run. The most common
use would be to keep the build node while terminating other
instances, then using rebuild to recreate them. Be careful of
puppet certificate errors if you do this - cert cleaning on the
master may be required.

Also added a check to make sure the right CI network is chosen,
which requires the keystone module in order to confirm which tenant
we are running as.

WIP: Add rebuild command
do not include white space in ceph user name

It will break with:

ProcessExecutionError: Unexpected error while running command.
Command: rbd create --pool rbd --size 1024 volume-32b2980d-0060-42a5-98fd-7408a03a8570 --new-format
Exit code: 1
Stdout: ''
Stderr: 'rbd: extraneous parameter cephx\n'

Which is confusing because the cephx parameter does not show in the
command displayed. It actually comes from the environment because
/etc/init/cinder-volume.override has

    env CEPH_ARGS="--id no user"

instead of

    env CEPH_ARGS="--id 'no user'"

Although an option would be to make sure it is quoted everywhere,
it is likely to break in so many places that it's probably not worth the
effort anyway.
