[Pacemaker] Two stonith devices

[Vladislav Bogdanov]

Replying to myself after studying TODO.

Could you guys (Dejan, Andrew) please describe possible ways for fixing
this, may be I'll be able to do it to some extent. I still need to study
code which is a kinda black magic where it goes to stonith.
May I ask for some pointers to start with?
And, is design of stonith subsystem documented somewhere? Can you
shortly describe it if it is not?

Best,
Vladislav
