Remove bm_poseur, unmaintained and obsolete

The bm_poseur git repository link has been broken
for over 11 months. The virtualized/fake baremetal
environment is not working and has not worked in a
long time. Now, on the tail of enabling 'enable -o errexit',
this functionality now has a hard break.

use "rabbit_hosts" config option instead of "rabbit_host"

This allows for easy client configuration against clustered RabbitMQ
setups.  Does not break existing configs.

Move heat keystone setup into lib/heat

Move the heat setup which currently happens in files/keystone_data.sh
to lib/heat, where we have create_heat_accounts.

Move the user, role, service and endpoint creation as that is consistent
with what other services, e.g lib/nova are doing.

fix tgt to use 'service' instead of upstart calls

the comments in here were largely about oneric, which we don't
support any more. service is installed in a precise environment,
and will support debian and the upcoming transition to systemd
better, so use that instead.

Use cat instead of read<file

When reading a file, it is expected that
the read process will exit 1 as this is
expected whenever the input reaches an EOF.

Because it is not clear if the 'exit 1' is
from a successful read or a more serious error,
and as this edge-case of 'read' is not well-known,
we instead change this code to read the file using
'cat'.

The new code is moved into a function, is_docker_running.

Furthermore, we now quote the variables and check
for the existance of the pid file for better and safer
error handling.

this should be is_service_enabled and not service_enabled. Not
sure why it passes in the gate, but it fails in stackforge jobs.
