This commit adds support to mount and delete volumes provisioned by older plugin versions (1.0.0) in order to support backward compatibility to 1.0.0 created volumes. It adds back the ability to specify where older meta data was specified, using the metadatastorage option to the plugin. Further, using the provided meta data to mount and delete the older volumes. It also supports a variety of ways in which monitor information may have been specified (in the storage class, or in the secret), to keep the monitor information current. Testing done: - Mount/Delete 1.0.0 plugin created volume with monitors in the StorageClass - Mount/Delete 1.0.0 plugin created volume with monitors in the secret with a key "monitors" - Mount/Delete 1.0.0 plugin created volume with monitors in the secret with a user specified key - PVC creation and deletion with the current version (to ensure at the minimum no broken functionality) - Tested some negative cases, where monitor information is missing in secrets or present with a different key name, to understand if failure scenarios work as expected Updates #378 Follow-up work: - Documentation on how to upgrade to 1.1 plugin and retain above functionality for older volumes Signed-off-by: ShyamsundarR <srangana@redhat.com>
