[common_test] Add netconf client, ct_netconfc

The netconf client supports basic netconf functionality over SSH. In
order to allow testing of both success and failure cases, it is
intentionally written to allow non-standard behavior.

In order for the netconf client to use the generic connection
mechanism in common_test, ct_gen_conn has been updated to be more
flexible:

Added options:
      {reconnect,bool()}
      {forward_messages,bool()}
      {use_existing_connection,bool()}

Allow handle_msg to return
       {reply,Reply,State} |
       {noreply,State} |
       {stop,Reply,State}

If forward_messages==true, the ct_gen_conn callback must also
implement:

   handle_msgs(Msg,State) -> {noreply,State} | {stop,State}
  • Loading branch information...
