Add `mGet()` and `mSet()` function to `redis` adaptor

Background

The redis adaptor supports basic Redis commands, it lacks support for the mGet() and mSet() commands, which are essential for efficiently handling multiple key-value pairs in Redis.

Feature Request

I propose adding two new helper methods to the Redis adaptor: mGet() and mSet(). These methods should mirror the functionality of Redis's native json.mGet and json.mSet commands, allowing us to retrieve and set multiple key-value pairs in a single operation.

Implementation Details

1. mGet(keys: Array<string>):

   • Accepts an array of strings, where each string is a key in Redis.
   • Returns an array of values corresponding to the provided keys.

2. mSet(keyValuePairs: Object):

   • Accepts an object where each key-value pair corresponds to a Redis key and its associated value.
   • Sets all the key-value pairs in Redis in a single operation.

Use Cases

• mGet(): This will be particularly useful when retrieving multiple related values from Redis in a single call, reducing the need for multiple jGet operations and improving performance.
• mSet(): This will allow us to efficiently store multiple key-value pairs at once, which is beneficial when working with bulk data.

Redis Docs

• https://redis.io/docs/latest/commands/json.mset/

Start by locating the Redis adaptor and its existing jGet operations. Add mGet for retrieving multiple keys and mSet for storing multiple key-value pairs in one operation, then verify that both methods match the requested inputs, returned values, and Redis JSON command behavior.
