upgrade/replace addon for Plone 5: WebServerAuth 1.7

[paregorios]

This addon is currently active in our 4.3 build. I assume it is part of the setup that makes NYU SSO (Shibboleth) work for us. Is that correct? If so, how do we get this functionality in 5.1?

See also #529

@paregorios I believe we no longer use this package since the transition from Apache based shibboleth authentication to Plone based SAML2 authentication. I would suggest removing it initially when setting up the Plone 5.1 migration instance.

@alecpm did you happen to remove this addon in setting up the migration server, or is this still an active todo (or a post-migration step)?

[alecpm]

It’s still a dependency, but should be safe to remove. We can test that out later today.

Maybe @chiruzzimarco cqn try removing it from the updated-ansible branch and see how that goes?
