Allow qpid to be selected as AMQP provider on precise

Fixes bug 1137667

Previously the auth/sasl config for qpidd was broken, and the
openstack services using RPC were not properly configured.

Now we ensure that:

- the admin qpid_username/password are configured for all services
  (as the qpidd ACL config denies all access to non-admin users)

- the PLAIN sasl mechanism is configured for qpidd (otherwise the
  qpid_password is not propogated)

- the qpidd process has read permission on the sasl DB (otherwise
  thw admin user/apss cannot be verified even if set)
