[Pacemaker] [Booth] Howto grant ticket to other site, if resource fails

After this discussion, I have created a daemon in order to achieve my goal.

Easy explanation of created daemon is as follows:
- Daemon monitors the resources that depend on the ticket.
- When it becomes impossible for the resource depending on a ticket to
start in a site, a ticket is moved to other sites.
- Pacemaker and Booth are required in order to use daemon.
- For the moment, it operates only in combination with Pacemaker-1.1
in about April, 2012.

If the old thing is enough, I think that I can show a source by the
end of March.
In that case, I'm hoping to be incorporated into the repository Booth.

In the future, we are planning to modified to work in combination with
the latest Pacemaker.

Yusuke
