Enabling PowerVM RMC

~~~~~~~~~~~~~~~~~~~~

To enable PowerVM RMC_, IPv4/IPv6 dual-stack mode must be enabled. To do this,

you must set ``use_ipv6`` using the ``nova_nova_conf_overrides`` variable:

.. code-block:: yaml

fixes:

- Setup for the PowerVM driver was not properly configuring the system

to support RMC configuration for client instances. This fix introduces

an interface template for PowerVM that properly supports mixed IPV4/IPV6

deploys and adds documentation for PowerVM RMC. For more information see

bug 1643988.
