Various fixes for issues with new architecture (#208)

* Add formatters to the TOC - fixes #204

* Add 'steps' settings to the example YAML in the docs. Fixes #206

* Improved docs on authentication architecture

* Fix setting modules on the command line - they now override any module settings in the orchestration as opposed to appending

* Fix tests for gsheet-feeder: add a test service_account.json (note: not real keys in there)

* Rename the command line entrypoint to _command_line_run

Also: make it clear that code implementation should not call this
Make sure the command line entry returns (we don't want a generator)

* Fix unit tests to use now code-entry points

* Version bump

* Move iterating of generator up to __main__

* Breakpoint

* two minor fixes

* Fix unit tests + add new '__main__' entry point implementation test

* Skip youtube tests if running on CI. Should still run them locally

* Fix full implementation run on GH actions

* Fix skipif test for GH Actions CI

* Add skipifs for truth - it blocks GH:
