APIv2 compatibility network connect|disconnect
Add endpoints for the compat layer for network connect and disconnect. As of now, these two endpoints do nothing to change the network state of a container. They do some basic data verification and return the proper 200 response. This at least allows for scripts to work on the compatibility layer instead of getting 404s.
