Consider adding batch support for `DELETE /responseStore` broker API

[yashmayya]

• Context is in Fix ResponseStoreCleaner bugs causing unbounded response store growth and cleanup failures #17622.
• In cases where there's a very large number of cursor responses stored on the brokers, the periodic controller job that is responsible for cleanup can get bogged down because it currently does a GET call on each broker to retrieve a full list of cursor responses and then issues an individual DELETE call for each cursor response that is past expiry.
• We can consider adding a batch delete API to make this controller-based broker cleanup job more efficient.
