Move pgsqlms to a different namespace?

[ioguix]

We are currently installing pgsqlms to the heartbeat namespace.

This choice is arguable for some reasons:

• it seems the heartbeat namespace is expected to host official RA from the resource-agents project
• heartbeat is a pretty misleading namespace as heartbeat is long deprecated in favor of Pacemaker
• there are on-going discussions about this heartbeat namespace (deprecating it? moving official RA to the Pacemaker namespace?). See: https://www.mail-archive.com/[email protected]/msg00241.html

We should probably create the PAF namespace and install pgsqlms in there by default.
