Support of Flask and python3 to integrate in CKAN v2.10.1

[Nisha1293]

I am trying to integrate the ckanext-oauth2 extension into CKAN v2.10.1. However, I am encountering "pylons and xmlrpclib" error while integrating extension.

In my analysis, I found that these errors are occurring due to flask and python3 changes in CKAN latest code whereas this extension is supporting python2 only.

I have asked CKAN community about this issue on ticket #7744. On this ticket community has suggested to changes in the extension to support Python 3 and Flask in order to make it compatible with CKAN's latest code.

Please confirm if it is okay to fix according to the issue confirmed in CKAN?
