Epic: Replace Redis with Cube Store

[rpaik]

Currently, Cube relies on Redis for in-memory caching and queue management, and this is inefficient and not scalable. Redis cluster coordination consumes a lot of resources under the high load and becomes the bottleneck to scaling the API concurrency.

Cube Store will replace Redis for in-memory caching and queue management and you will find more details in this blog post.
