With the recent refactoring [1] of the Pacemaker collectd plugin, the
GSE filter may receive Pacemaker metrics from the other nodes of the
cluster. The Heka filter needs to be updated to discard these messages
otherwise the GSE filter flaps between active and inactive state.

Closes-Bug: #1616860
This change adds a collectd plugin that gets metrics from the Pacemaker
cluster:
- cluster's metrics
- node's metrics
- resource's metrics
Most of the metrics are only collected from the node that is the
designated controller except pacemaker_resource_local_active and
pacemaker_dc_local_active.
The plugin also removes the 'pacemaker_resource' plugin by providing the
exact same metrics and notifications for the other collectd plugins.
Finally the plugin is also installed on the standalone-rabbitmq and
standalone-database nodes if they are present.
