Adds a plugin to specify what SAN policy is applied by the OS when a new disk is discovered. The behaviour is controlled by the configuration option "san_policy". Possible values are: - Not set (None): no policy configuration is set - OnlineAll: mounts all discovered disks - OfflineShared: mounts all disks except shared ones - OfflineAll: does not mount any discovered disk Change-Id: I484eb72eb81290799032f49eff3b4d2e28b46fe3 Implements: blueprint san-policy Co-Authored-By: Matei-Marius Micu <mmicu@cloudbasesolutions.com> Co-Authored-By: Stefan Caraiman <scaraiman@cloudbasesolutions.com>
