Closes-Bug: #1373750
libvirt plugin "parallels" support

We're in the process of establishing the CI testing with
Parallels Cloud Server plugin for libvirt.
Currently we use local clone of devstack in our infrastructure,
but we want to switch to upstream

requires extra customization of nova.conf and glance-api.conf:
nova.conf should have "images_type" and "connection_uri"
defined, and glance-api.conf to have "ploop" in disk formats

Implements: blueprint pcs-support

remove nova baremetal driver support

This has been deleted from the nova tree, we should purge it from
devstack, as it will not work any more.
