driver notes in feature support matrix don't render

[Matt Riedemann]

It looks like at some point the 'driver-notes.*' entries in the feature support matrix docs stopped working:

https://github.com/openstack/nova/blob/master/doc/source/user/support-matrix.ini#L142

I don't see it in queens or pike:

https://docs.openstack.org/nova/queens/user/support-matrix.html#operation_attach_volume

https://docs.openstack.org/nova/pike/user/support-matrix.html#operation_attach_volume

I thought maybe this was just an issue on master after converting the code to use a library:

https://github.com/openstack/nova/commit/c09fe87feb8d01254f1654967eacf71b504160d6#diff-27c82340c9620cf5f0e76ff972b4247f

And that library doesn't parse driver-notes even though it has a constant for it:

https://github.com/openstack/sphinx-feature-classification/blob/master/sphinx_feature_classification/support_matrix.py#L31

But that doesn't explain why the driver notes don't render in queens or pike.

This is where the nova feature support matrix code was parsing driver notes in queens:

I think this got fixed by the patch linked in comment 1.
