Add nl01.opendev.org to our inventory

This is a new focal replacement for nl01.openstack.org. We keep
nl01.openstack.org in our inventory for now because we want ansible to
update the nodepool.yaml configs for these two hosts to coordinate a
hand off of responsibilities once we are happy with the new deployment.

We also switch the testing hostname to nl04.openstack.org as this will
be the last nodepool launcher to be removed. When we swap it out the
testing will be updated to use focal hosts.

Depends-On: https://review.opendev.org/c/openstack/project-config/+/779863
