docs: python bindings howto

* Confirmed that updates to the tests have significant'y improved that
  output.
* Updated some of the additional notes for the section on hkp4py.
** This is in anticipation adding at least import examples using that
   module as well.  It may also include adding examples of exporting a
   key and uploading it to the keyservers.
