[Pacemaker] [PATCH] crm shell (configure node) for Heartbeat stack

[Dejan Muhamedagic]

Hi Kazunori-san,

Can you please test the attached patch. I'm not sure if it covers
all cases, but I believe that it is the right direction. I tested
it lightly, but I don't have a Heartbeat cluster at hand right
now.

Sorry again for taking such a long time. For whatever reason it
was difficult for me to figure this one out.

Thanks,

Dejan
