Code fix for attach and detach volumes

Cherry-picked to split up commit https://gerrit.onap.org/r/#/c/31149/
into individual jira tickets.

open stack consumes cdp-pal openstack jars to connect to cinder,
this fix retrives set of volumes from volumeservice provider
and performs attach or detach through compute service.
