+1 for removing XML tests from Tempest.

Now Tempest contains XML tests for Nova, Keystone, Cinder, Neutron and
Ceilometer. On the other hand, it contains JSON tests for all projects.

XML supports of both Nova and Keystone have been marked as deprecated in
Icehouse. and the XML support of Neutron has been removed already.
So the remaining projects are Cinder and Ceilometer only for Tempest XML tests.

I don't think it is easy that clients switch JSON/XML for each project,
and I think it is a right direction to concentrate on JSON.
