Add Redis caching

[Theory903]

Currently we rely on local memory or basic storage for the behavior engine. Adding Redis caching would greatly improve our performance and allow for distributed deployment of the gateway. A good starting point would be the cache connection and basic get/set operations.

Hi, I would like to help you with the issue.
My understanding is that we want introduce Redis caching so that behavior engine can store and retrive results instead of recomputing them every time.
I can add redis dependency, create redis connection modules, implement basic cache helpers(get, set, delete) and make them available to use for the behavior engine to use.
Please let me know if this approach matches the expected implementation.
