wireproto: remove iterbatch() from peer interface (API)

Good riddance.

Some tests have been ported to the new API. This probably should
have been done in earlier commits. But duplicating the test coverage
would have been difficult. It was easier this way.

.. api::

   The wire protocol peer's ``iterbatch()`` for bulk executing commands
   has been remove.d Use ``peer.commandexecutor()`` instead.
