Description
We have seen that during refresh_token grant type, the parameters are sent in query string and are logged by our monitoring systems. For token requests (specially over internet) x-www-form encoding should be used and currently it's used for code grant type too.
This PR updates the refresh_token grant type to use x-www-form
