 Description   

In ClusterStor system a node in UNCLEAN state can be STONITHed after it has passed power down and power up already.
The patch adds ha_power_up_delay() in order to delay node's power up until CRM state became OFFLINE when failover pair is set and for $NODE_UP_DELAY seconds otherwise.
LOAD_TIMEOUT is added in order to ha_load_timeout be tunable.
The failover pair list for all victims are to be set via new -f option.
