When using Google Cloud Platform Redis Memorystore, 'ERR unknown command: client' is thrown.
This is caused by architecture of Memorystore, as GCP docs say:
Some commands can interfere with a managed Redis service and are blocked.
CLIENT command is in the list of blocked commands.
Suppressing this error has no negative effect on main functionality, as it has been said in corresponding issue #1002
it is not critical, just used to name the different workers
and confirmed by us with extensive usage in both test and production environments.
