This is next step patch from https://review.openstack.org/#/c/573118/ which makes all the volume service clients alias with _latest suffix. As all the volume clients point to v3 service client only, having alias with _v2_ or _v3_ name are confusing. This commit provide alias with _latest suffix and use them in tempest. As old alias are being used in tempest plugins also, we keep the old alias also and slowly will move each plugins to start using new alias. Change-Id: Ib89ab72ab4ada3e8442901f104b0b96072187ef9
