OCPBUGS-14049: Add secret informer

Add a secret informer for the secret that we store credentials in,
'openshift-cluster-csi-drivers / manila-cloud-credentials', like we
already do for the Cinder CSI Driver Operator. As is the case there,
this ensures our controllers will reload upon changes to the secret.
