This commit implements composable HA for the pacemaker profiles. - Everytime a pacemaker resource gets included on a node, that node will add a node cluster property with the name of the resource (e.g. galera-role=true) - Add a location rule constraint to force running the resource only on the nodes that have that property - We also make sure that any pacemaker resource/property creation has a predefined number of tries (20 by default). The reason for this is that within composable HA, it might be possible to get "older CIB" errors when another node changed the CIB while we were doing an operation on it. Simply retrying fixes this. - Also make sure that we use the newly introduced pacemaker::constraint::order class instead of the older pacemaker::constraint::base class. The former uses the push_cib() function and hence behaves correctly in case multiple nodes try to modify the CIB at the same time.
