We don't actually need version 3. Mark it as version 2 to keep it
inline with everything else. In general we should only increase
past v2 if we need a specific feature.

Currently we deploy the openstacksdk config into ~nodepool/.config on
the container, and then map this directory back to /etc/openstack in
the docker-compose. The config-file still hard-codes the
limestone.pem file to ~nodepool/.config.
Switch the nodepool-builder_opendev group to install to
/etc/openstack, and update the nodepool config file template to use
the configured directory for the .pem path.
Also update the testing paths.

This was missing but is part of the required runtime directories for
the container (for now, until we maybe move all this to volumes).
