Bug#850089: #850089 ITP: flask-restplus - upstream version considerations

[Carl Suster <carl@contraflo.ws>]

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.
