ERROR stevedore.extension [-] Could not load 'noop': No module named vif_plug_noop.noop in n-cpu logs

Noticed in gate runs in the n-cpu logs [1]:

The ovs and linux_bridge plugins however were loaded successfully.

Recently, a noop plugin was added to os-vif but the vif_plug_noop module was not added to the packages list in setup.cfg, which is my guess as to why this error is happening.
