Make sure rpcbind is installed and running

Rpcbind is a dependency of pacemaker, so the package should be
installed anyway. But i discovered that if the sevice gets stopped
(manually or otherwise), re-running Puppet won't start it up again. So
we should explicitly make sure that we install/enable/run rpcbind.
