Doit support role versions

[bit-cloner]

There seems to be two naming conventions of doit support role . this script seems to hardcode the role name as DoiT-Support-Gateway
grant(){

echo -e "\nGranting permissions to the cluster : $cluster \n"
./grant-ro-accesses.sh --grant ${region} ${cluster} arn:aws:iam::$account:role/DoiT-Support-Gateway

}

This role doesn't exist in AWS accounts with concedefy access.

I think this role name should be DoiT-Support*
