Code Issues Proposed changes

Allow special purpose container interfaces 

Some use cases such as public facing dns servers for Designate
are difficult to deploy with the dynamic inventory as they have
a hard requirement for fixed IP on certain interfaces. An additional
variable allows the deployer to create these special interfaces.

features:
- If defined in applicable host or group vars the variable
``container_extra_networks`` will be merged with the existing
``container_networks`` from the dynamic inventory. This allows a deployer
to specify special interfaces which may be unique to an indivdual
container. An example use for this feature would be applying known
fixed IP addresses to public interfaces on BIND servers for designate.
