Description

High: PE: Apply only stickiness values (not failure-stickiness) to the whole group, not the individual resources
Failure_stickiness values still apply to the individual child resources.
This allows for much simpler calculation of when groups migrate _and_ partially
active groups when there is no other alternative (no other node to migrate to).
N ::= Number of resources in the group
M ::= Maximum number of failures by any member of the group
Assuming no rsc_location constraints, the group will migrate when (N * stickiness) < (M * failure_stickiness)
