title: Alternative to pytest namespace after upgrade to 3.7.4 - Error: unknown hook 'pytest_namespace'
body: <p>I did an upgrade to the latest 3.7.4 and I have seen that pytest namespaces are deprecated <a href="https://docs.pytest.org/en/latest/deprecations.html#pytest-namespace" rel="nofollow noreferrer">https://docs.pytest.org/en/latest/deprecations.html#pytest-namespace</a></p>
  
  <p>I geet an error when I run pytest against a module:</p>
  
  <pre><code>pluggy.manager.PluginValidationError: unknown hook 'pytest_namespace' in plugin &lt;module 
  </code></pre>
  
  <p>I have a small conftest.py file where I parse out some variables from database locations and similar. An then I use those variables (from def pytest_namespace() function) inside the pytest module file.
  But then I get the hook error test.</p>
  
  <p>Is there some alternative to use, so that I do not have to rebuild a lot of code?</p>
  
  <p>Thanks in advance.</p>
