Set meta container-attribute-target=host attribute

This is needed because when we run bundles we actually
want to store attributes on a per-node basis and not on a per-bundle
basis. By activating this attribute pacemaker will pass
some extra OCS_RESKEY_CRM_meta attributes that will help us in this
decision.

We can merge this once we have packages for pacemaker and
resource-agents releases that contain the necessary fixes.

Proper pacemaker and resource-agents are now in the repo [1] so
we can merge it and backport it to pike.
