Thanks for submitting an issue!

Here's a quick checklist in what to include:

• Include a detailed description of the bug or suggestion

I've got a setuptools plugin project using module-level hooks and 'pytest_cmdline_parse' is not getting called. All other bootstrapping hooks and initialization hooks are called, but not this one. I went through #2616 but this is different because I am calling it from a setuptools plugin. Is there something special about this hook that I should know about? Thank you very much!
