Description of problem:
An option to cman_tool that allowed for a configurable timeout on the
wait commands (cman_tool wait, cman_tool -w join and cman_tool -w
leave) would be a useful feaure for initscripts.  This would give the
script the ability to terminate a cman_tool operation if it failed to
establish a connection or quorum on boot or shutdown.  

For eample: Quorum is needed in order for GFS to mount.  If the script
is unable to detect that the cluster is quorate after a predetermined
amount of time it should be allowed to fail so that the node can
continue to boot.   Failure to do so will result in operable nodes
until quorum is restablished.  In situations where only one node is
able to boot in the cluster, that the node will not be accessbile
unless booted into single user mode or run level 2.

Adding a timer to cman_tool is the easiest way to do this, but other
work arounds can be implemented in the initscripts if need be.
