Description of problem:


Corosync logs contain messages like so:

Feb 13 08:25:51 notice  [MAIN  ] Corosync Cluster Engine exiting normally
Feb 13 08:32:10 notice  [TOTEM ] Initializing transport (UDP/IP Multicast).

It would be useful to:
- include the pid file so we can differentiate between different instances of corosync
- include the host name so that CTS can look for node-specific patterns
- include the process name if possible.  this makes post-filtering easier as it is useful to have pacemaker log to the same file.
  
Actual results:

Feb 13 08:25:51 notice  [MAIN  ] Corosync Cluster Engine exiting normally

Expected results:

Something like syslog or perhaps:

Feb 13 08:25:51 [22196] pcmk-3 corosync notice  [MAIN  ] Corosync Cluster Engine exiting normally
