deploy: support for read affinity options per cluster

Implemented the capability to include read affinity options
for individual clusters within the ceph-csi-config ConfigMap.
This allows users to configure the crush location for each
cluster separately. The read affinity options specified in
the ConfigMap will supersede those provided via command line arguments.
