Lightweight install for magnum-cluster-api-proxy

[jrosser]

If I make a virtualenv for the proxy I get the whole of m-capi plus magnum and all the openstack client libraries.

Is there a way to just install the proxy tool and not the rest of it. Feels like it ought to be a pretty minimal set of dependancies.

well, i don't think that kind of installation is supportable. It requires split the proxy from the driver.

@okozachenko1203 maybe we can make magnum and dev dependency?
