currently we are deploying external-attacher
as a seperate statefulset, which leads to
attacher communicating with the node provisoner
daemonset, This PR deploys external-attacher
as a sidecar container inside provisioner
statefulset, so that external-provisioner
always communicates with the plugin responsible
for the provision controller capcabilities.

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

as the socket directory will be created
inside the container no need to follow
the plugin name in for the directory
creation, this will also reduce the code
changes if we want to change driver name.
