Upstream patch: https://github.com/ClusterLabs/pcs/commit/5eb51289926d5e1e68092db5d1d177fddc31a766 It's the same patch as for bz2018969 Test: Pcs returns an error when a resource / stonith agent provides metadata not matching to OCF 1.0 / 1.1 schemas shipped with pcs. These schemas are a bit relaxed comparing to official OCF schemas, their purpose is to make sure metadata are parsable by pcs.
