cmannotifyd: deliver cluster status at startup and fix daemon init
 
From: "Fabio M. Di Nitto" <fdinitto@redhat.com>

cmannotifyd is very often (if not always) started _after_ cman is
completely settled. That means cmannotifyd does not receive/dispatch
any notifications on the current cluster status at startup.

change cman connection loop to generate a fake notification that
config and membership have changed (we can't poll if they did)
and use those information internally too, to reinit logging with
new cman connection.

Resolves: rhbz#819787
