[Pacemaker] Feature request: cleanup resource on primitive definition change

[Vladislav Bogdanov]

Hi Andrew, all,

I'm now testing latest changes in git, everything goes much cleaner then
a week ago, I'll (hopefully) make report later.

One feature came into mind during testing:
Imagine resource which was tried to be started on all nodes and failed
everywhere.
Then administrator changes resource definition to fix start problem.
Now, resource is not tried to start until it is cleaned up (or both its
failure-timeout passes and cluster state re-checked).
Idea is to make automatic resource cleanup after definition change.

That would help those who use some automatic tools to manage pacemaker
resources.

Btw, I did not find cluster-recheck-interval in pacemaker explained
"Cluster options" chapter together with stop-all-resources,
maintenance-mode and placement-strategy. Former option described only in
chapter about rules, others are not mentioned at all.

Best,
Vladislav
