fake_network_cache_model doesn't support ipv6

[Ellen Hui]

Currently, the functions in fake_network_cache_model all default to building a fake ipv4 network, and so the easiest way to test against a fake ipv6 network is to manually create ipv6 components (subnets, routes, ips) and plug them into the default fake VIF. This makes testing ipv6 functionality rather error-prone and laborious.

There should be some option in the fake_network_cache_model functions that creates ipv6 models instead of ipv4 models.

    Add ipv6 support to fake network models

    Currently, the functions in fake_network_cache_model all default to
    building a fake ipv4 network, and so the easiest way to test against a
    fake ipv6 network is to manually create ipv6 components (subnets,
    routes, ips) and plug them into the default fake VIF. This makes testing
    ipv6 functionality rather error-prone and laborious.

    This patch adds an option to create ipv6 models.
