shield Recommended update for yast2-drbd

SUSE-SLE-HA-12-SP1-2016-312

This update for yast2-drbd allows users to configure whether lvmetad should be used or not. When lvmetad is enabled, the volume group metadata and PV state flags are obtained from the lvmetad instance and no scanning is done by the individual commands. Because lvmetad's cache cannot be synchronized between nodes, users are advised to disable lvmetad in cluster environments.
