Thought on requirements.txt

[djowett]

I'm not sure, but it seems to me that if plone_download_requirements_txt is changed to no in the configuration then we should make sure that requirements.txt is overwritten by the template rule here

I think this should work

- name: Copy requirements file from template
  when: not requirements_txt.stat.exists or not instance_config.plone_download_requirements_txt
  [...]

Any thoughts?
