[Pacemaker] Constraints on cluster options

[Evgeniy Ivanov]

Hello,

As I understand there is no constraints on cluster options, correct?
Resource FOO should be started only after B is started and event E
happened. Currently E is a node attribute set by some BAR resource on
all nodes, which looks ugly.
It seems that making E a cluster attribute/option and setting
constraint on it is much better solution. Is it supported or are there
alternatives?
