Provide options to pass in Ceph cluster-id This commit provides the option to pass in Ceph cluster-id instead of a MON list from the storage class. This helps in moving towards a stateless CSI implementation. Tested the following, - PV provisioning and staging using cluster-id in storage class - PV provisioning and staging using MON list in storage class Did not test, - snapshot operations in either forms of the storage class Signed-off-by: ShyamsundarR <srangana@redhat.com>

#
# This is to be used when using `clusterID` instead of monitors or
# monValueFromSecret in the StorageClass to specify the Ceph cluster to
# provision storage from, AND when the value of `--configroot` option to the
# CSI pods is NOT "k8s_objects".
#
# This patch file, patches in the specified secret for the 'clusterID' as a
# volume, instead of the Ceph CSI plugin actively fetching and using kubernetes
# secrets.

Addressed using k8s client APIs to fetch secrets Based on the review comments addressed the following, - Moved away from having to update the pod with volumes when a new Ceph cluster is added for provisioning via the CSI driver - The above now used k8s APIs to fetch secrets - TBD: Need to add a watch mechanisim such that these secrets can be cached and updated when changed - Folded the Cephc configuration and ID/key config map and secrets into a single secret - Provided the ability to read the same config via mapped or created files within the pod Tests: - Ran PV creation/deletion/attach/use using new scheme StorageClass - Ran PV creation/deletion/attach/use using older scheme to ensure nothing is broken - Did not execute snapshot related tests Signed-off-by: ShyamsundarR <srangana@redhat.com>
