[illusional]

Relies on #69 being merged, that will cleanup the commit history, otherwise the short history:

Summary:

• Renamed translate_workflow -> translate_workflow_internal
  • Added namedtuple for naming output type of this method

• Turned @staticmethods into @classmethods for consistency
• Fixed tests
• Removed unused params

And added the Hail Batch translator.

Hi @illusional , the tests failed because anis_assistant in master branch is still calling translator.translate(...) https://github.com/PMCC-BioinformaticsCore/janis-assistant/blob/b51402a90b6f8ea08e1d1b8a261817ebcc6a565e/janis_assistant/management/workflowmanager.py#L1159.
So, I tried to run one of the tests locally with your branch from janis_core and I modified janis_assisstant to call translator.translate_worfklow(...), I ran into another errror:

  File "... /janis-core/janis_core/translations/translationbase.py", line 125, in translate_workflow
    raise Exception(f"Please use the call the '{self.__class__.__name__}.translate_{tool.type.lower().replace('-', '_')}(**kwargs) instead of translate_workflow(**kwargs)")
AttributeError: 'function' object has no attribute 'lower'

Can you look into what changes we should make in janis_assistant to fix this error?
Thanks :)
