ceph-handler: group listen topics and condition We are using multiple listen topics with the handlers. That means that we are notifying 4 tasks for each handler. Instead we can group the listen on an include_tasks and based on the group condition.

handler: fix bug 411bd07d54fc3f585296b68f2fd04484328399b5 introduced a bug in handlers using `handler_*_status` instead of `hostvars[item]['handler_*_status']` causes handlers to be triggered in anycase even though `handler_*_status` was set to `False` on a specific node.
