[PATCH v2 4/6] auto-t: allow configurable DBus timeout/callbacks on connect{_bssid}

Let the caller specify the method timeout if there is an expectation
that it could take a long time.

For the conventional connect call (not the "bssid" debug variant) let
them pass their own callback handlers. This is useful if we don't
want to wait for the connect call to finish, but later get some
indication that it did finish either successfully or not.
