    Fix IPAddress and CIDR type decorators

    Use load_dialect_impl() user hook instead of calling
    with_variant() on a type implementation in IPAddress
    and CIDR type decorators. This makes this code work
    with SQLAlchemy 0.8.x versions.

    Fixes bug 1200231

Fix proposed to branch: stable/grizzly
Review: https://review.openstack.org/53167

[Xavier Queralt (xqueralt-deactivatedaccount)]

I've hit this issue with grizzly running in fedora 19 which has sqlalchemy 0.8.2. Without the fix the system is completely unusable as it is impossible to boot an instance.
