SUNSUBSCRIBE
shardchannel
[shardchannel…]
Unsubscribes the client from the given shard channels, or from all of them if none is given.
When no shard channels are specified, the client is unsubscribed from all the previously subscribed shard channels. In this case a message for every unsubscribed shard channel will be sent to the client.
Note: The global channels and shard channels needs to be unsubscribed from separately.

When successful, this command doesn’t return anything. Instead, for
each shard channel, one message with the first element being the string
sunsubscribe
is pushed as a confirmation that the command
succeeded.
