docs: Load given file into knowledge base.
  
      Simply load data into an existing knowledge base:
  
      .. code-block:: console
  
          $ inveniomanage knowledge load mykb /path/to/file.kb
  
      The file is expected to have a mapping with values: ``foo<seperator>bar``
      (per line).
  
      ``<separator>`` is by default set to **---**, but can be overridden with
      ``-s someseperator`` or ``--sep someseperator``.
