Jumping in now as I'm helping with py3 support efforts in the manila side.

In manila we have both support for Apache WSGI and the built-in server
(which depends in eventlet). Would it be a possible workaround to rely on
the Apache WSGI server while we wait for evenlet issues to be sorted out?
Is there any chance the upper constraints will be updated soon-ish and this
can be fixed in a newer eventlet version?

This is the only change it's preventing us to be fully py3 compatible,
hence it's a big deal for us.
