Description

This PR includes following refactors -

• Currently, publish method of redis takes in only one key to publish to a channel. Instead it should take in a list of keys to be published so that we can call publish once for all keys instead of calling once for every key.
• Add a new method on redis interface to delete multiple keys
• Created three separate methods: one for handling database calls with Redis redaction and publishing to IMC invalidation channel, another for Redis redaction and publishing, and the last one solely for publishing. This hierarchy provides flexibility for clients to perform either comprehensive invalidation or targeted actions.
• In the redis subscriber logic, match on the channel name and perform the appropriate action
