This is wanted for flexget, which currently pins its dependency on
flask-restplus==0.8.6. I have opened an upstream issue to ask that this be
updated to the newest flask-restplus version 0.9.2:
https://github.com/Flexget/Flexget/issues/1615
This will require some changes to flexget as it was patching some internal
methods of flask-restplus which have changed.
If upstream does not want to change the dependency soon, then I will initially
package flask-restplus at the older version 0.8.6 until I can work out how to
help make the change with upstream.
