Existing config maps are now replaced with rados omaps that help store information regarding the requested volume names and the rbd image names backing the same. Further to detect cluster, pool and which image a volume ID refers to, changes to volume ID encoding has been done as per provided design specification in the stateless ceph-csi proposal. Additional changes and updates, - Updated documentation - Updated manifests - Updated Helm chart - Addressed a few csi-test failures Signed-off-by: ShyamsundarR <srangana@redhat.com>
