Nova - Add ephemeral pool creation

- remove the ephemeral pool support from the rbd-provisioner helm
  chart. This was initially added to the rbd-provisioner helm chart
  to support initial integration efforts.
- remove the info for the ephemeral pool(s) from the rbd-provisioner
  overrides.
- update the nova overrides to include the necessary info for
  creating the ephemeral pool. Right now only one pool is included,
  but the nova chart supports multiple.
