Live migration does not work after kilo->liberty upgrade

[Jiří Stránský]

I've traced the issue to backwards incompatible changes in puppet-cinder. First a change that unconditionally sets host for cinder backends to a computed non-overridable value:

https://review.openstack.org/#/c/209412/

And a change that migrates from `host` to `backend_host` and makes the value configurable, but it keeps the old (wrong, backwards incompatible) behavior for default value of the property.

https://review.openstack.org/#/c/231068/

I think these should be both reverted, but since they already made it into stable/liberty and stable/mitaka, it's probably easiest to just work around this in t-h-t :-/

    Keep setting backend_host to 'hostgroup' for rbd backends

    There are backwards incompatible patches [1][2] in puppet-cinder which break
    upgrade scenarios, but at this point they made it to liberty and mitaka,
    so workaround in t-h-t is easier than revert
