"Revert "kolla: Increase resources for nordix-vpod"""

I give up trying to increase the resources for the vpod.
Openstack/kolla installation and functest seems to work
well with 4GB RAM and 30GB HDD, of course real baremetal
installations will have a lot more resources as required
for a stable installation.
