Flask-restful in requirements.txt causes problems: need fix

Kudu builds with flask-restful but the app fails with these messages in log:

The fix is to correct flask-restful to flask_restful. I don't have permissions to submit a pull request so someone needs to do this.

(I spent many frustrating hours troubleshooting this issue -- and this was my first Python deployment to Azure App Service)

Not sure about this as the package name is really "flask-restful": https://flask-restful.readthedocs.io/en/latest/installation.html...
