quantum native types prefetch the quantum conf before it exists

[Michael Chapman]

when creating networks, subnets and routers using the native types, the quantum.conf values are prefetched at the start of the puppet run, at which point it may contain no data. This is never re-read and can cause issues when using those types.

    Remove native type prefetches

    The network, router, subnet and router interface
    providers attempt to prefetch the configuration,
    which can result in empty or stale values being
    loaded as quantum configuration. The former will
    result in errors stating the quantum.conf file
    is incomplete, while the latter will often
    result in authentication errors.

    This patch removes the prefetching in the child
    classes and explicitly sets the conf to nil in
    the parent quantum provider so that it will be
    loaded at the correct time.
