Description Sylvain Bauza 2018-05-18 14:11:45 UTC 
Upstream will deprecate usage of eventlet of all the WSGI-run services, including nova-api and nova-metadata-api.
See https://review.openstack.org/#/c/549510/ for more details.

OSP13 runs nova-api through HTTPd already [1], so we're clear for the the former, but the latter (nova-metadata-api) requires a bit of work [2].

[1] https://github.com/openstack/tripleo-heat-templates/blob/master/docker/services/nova-api.yaml#L112

[2] https://github.com/openstack/tripleo-heat-templates/blob/master/docker/services/nova-metadata.yaml#L85

To make it clear, given upstream change, our customers would see a warning in the metadata service logs if we don't fix that for OSP14, which I guess is a bad experience for them as it could confuse them.
