envoy.config.filter.network.redis_proxy.v2.RedisProxy is deprecated

[cr-simmons]

V3 Details: https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/network/redis_proxy/v3/redis_proxy.proto

It appears that simply changing to type.googleapis.com/envoy.extensions.filters.network.redis_proxy.v3.RedisProxy is not sufficient as the proxy still fails.
