Updated the version for CRD. Updated tests to avoid failure due to late notification from Kubernetes and made one replica of app used for testing of caching functionality

I don't think this is defined yet?

Actually I think the real problem is that the original design of the connect_redis.lua lua script is not taking the cache into consideration.

In this case, the same incoming URL will have equal opportunity to route to one of the 2 pods. And if the first response is to be cached, subsequent requests should be serving from cache and should not consult with the routing decision again.

I think we can call ts.http.set_cache_url inside the lua script to fix this problem.
See the description of the call here - https://docs.trafficserver.apache.org/en/latest/admin-guide/plugins/lua.en.html#ts-http-set-cache-url

Basically in do_global_read_request function of connect_redis.lua, at the beginning we can call ts.client_request.get_pristine_url to retrieve the url and then call ts.http.set_cache_url at the very end of the function to properly set the cache key to the incoming URL.
