Add master node service passwords from yaml

astute.yaml now provides passwords for the
following services:
* mcollective
* astute
* cobbler
* postgres (keystone, nailgun and ostf DBs)

All statically defined passwords for these
services are now sourced from astute.yaml
Corrected small bug for astute user/pass in
rabbitmq role.

Adjusted Cobbler bootstrap profile to include
mcollective credentials.
