[Pacemaker] adding ldirectord resource to pacemaker

[Jayakrishnan]

Hello Geek,

I just stared the same project in el5 itself yesterday. I wonder if we could
go on as explained in Andrew's 'Cluster from scratch', it will give you an
active/active cluster. Wouldn't it gives you loadbalancing.

Pardon me if this is a stupid suggestion!!
