chore: Upgrade to Numaflow 0.11 and Fix: Trainer Pod getting the slave redis client connection

[shashank10456]

Fix for the issue:

Root cause of why the trainer pod is getting the slave redis client connection. The root cause for this is the way that we are importing the modules(preprocess, inference etc). When we are importing modules(Ex. inference), we are executing the global variable in inference module REDIS_CLIENT which in turn calculates global variable SENTINEL_CLIENT in Sentinel.py. There is a catch here. In python, the global variables are module scoped, because of this, when we are trying to calculate get_redis_client_from_conf in trainer.py module it is giving you the value of SENTINEL_CLIENT which it already calculated while importing inference module. Because of this, no matter what params you pass in while calling the get_redis_client_from_conf method, the client is returning the value it already has.
