Update devstack-plugin-vmax to reflect VMAX to PowerMax rebrand
Update the devstack script to point to the correct PowerMax drivers and to leverage the new PowerMax tags in cinder.conf merged in https://review.openstack.org/#/c/620659. Will change the name of the git repo at a later date. Change-Id: I0139e1ffd04ac7eb33021cd276e5b27379da79d0
