re-add pacemaker configuration system (pcs)
re-add pacemaker configuration system (pcs)

The python-pcs package is the packet construction set [1]. This package
has been shipped with Debian/Ubuntu for quite a long time. For some
reason the pacemaker/corosync configuration system [2] has been packaged
for Ubuntu under the name `python-pcs'. Use the correct name (that is,
`pcs', like its RPM counterpart) to resolve the collision.
