[PATCH v5 26/35] transport-helper: refactor process_connect_service

[Brandon Williams]

A future patch will need to take advantage of the logic which runs and
processes the response of the connect command on a remote helper so
factor out this logic from 'process_connect_service()' and place it into
a helper function 'run_connect()'.
