makeapi: optimize API.txt

Change Param formatting to:
* always use quantified names rather than the `required` and `multivalue`
  kwargs,
* ignore kwargs with default value,
* ignore kwargs related to validation, as validation is now strictly
  server-side,
* ignore the `attribute` and `primary_key` kwargs, as they are relevant
  only on object params,
* ignore the `include` and `exclude` kwargs, as makeapi takes into account
  only params available in the 'cli' context,
* ignore the unused `csv` kwarg.

Format optional Output arguments as kwargs.
