[NRTM] Added script for fixing RWS/Coder permissions

Jira MCC:https://jira.mdsol.com/browse/MCC-126040

Originally discovered from the Janssen/Coder CIRT.

Related to the code fix which will be deployed in R3: https://github.com/mdsol/Rave/pull/2556

If the code fix is deployed, any clients which do NOT have the Coder User setup on their studies they are coding for will instantly start failing to code. This will be a big problem if we do not fix the permissions first.

This script fixes those permissions. It will map Coder User to all Studies which are showing a history of being coded for. 

We should also probably inform the client that going forward they will need to map this user for their studies they would code on.

Please give feedback on the script @pramod @tashraf. I'd like to confirm that working with the CodingRequests table is the right way to figure out which studies they have. Will this work for all clients in all cases?
'@roleID' and '@userID' could be fetched once rather than each time per loop.
