Use devpi, drop calgDeps

As it says on the tin. We could follow some other DA projects and just install packages in an almost normal way with mirror instead of building and tagging our own wheels all the time. As posixshmem is not published on pypi, I'd just use proxy for now and eventually maybe replace it with the similar thing found in recent multiprocessing (IIRC, there's slight difference in behavior on opening / closing, will have to check exception handling).

What is the rationale to use devpi over the proxy for the PyPI-hosted packages? Caching?

Mostly for caching, yes. We could also potentially use it to internally "publish" packages like machine learning projects seem to like, though I don't have any plans to do so atm.

Either way, I'm open to either - mostly merged prematurely in order to be able to tag and simulate regular karabo install calng [tag] for convenience and better testing.
