[Pacemaker] Can Corosync bind to two networks

[Steve Davidson]

We want to run the Corosync heartbeat on the private net and, as a 
backup heartbeat, allow Corosync heartbeat on our "public" net as well.

Thus in /etc/corosync/corosync.conf we need something like:

bindaddr_primary: 192.168.57.0
bindaddr_secondary: 125.125.125.0

Our thinking is: if the private net connection fails but everything else 
is okay then we don't need to disrupt services since the private net 
failure won't affect our users.

Is there any way to do this?  Otherwise we need two interfaces connected 
to separate switches just for an (HA) heartbeat.  We don't want to 
recover services when everything is working except the private net or 
interface.
