Restore patch_redis_for_azure() in Floware.

When CLOUD_PROVIDER=azure and REDIS_PASSWORD is unset, CacheManager creates a Redis pool without a credential_provider. Floware then starts both Redis consumers with that pool, while the Celery worker still applies the patch. Floware can therefore fail Azure Redis authentication while Celery works.
