Description:

As radix.v2 is deprecated for a time, upgrading to radix.v3 give benefits on performance and maintenance.

The biggest change will be Pool interface . Pool in radix.v3 implements implicit pipelining, no need to explicitly Get and Put connections from pool.

Changes:

• intrefaces: RateLimitCache, Pool ..
• server initialization
• unit and integration tests, mocks

I'm glad to write a POC pr if we think it's worth doing.
