This PR intends to add support for calling DescribeConsumerGroups for groups created with the new consumer protocol and add backward compatibility to describe group created with the old Classic Protocol.
The working of the API remains similar. Users will continue to call the existing DescribeConsumerGroups api but internally we will be calling the new ConsumerGroupDescribe api to fetch the results. If we get GRP_NOT_FOUND or UNSUPPORTED_VERSION error, then in that case we will call the old DescribeConsumerGroup api.
