Subject: add network connect|disconnect compat endpoints

this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.

additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.
