Add sharded pubsub keychannel count to client info (#10895) 

When calling CLIENT INFO/LIST, and in various debug prints, Redis is printing
the number of pubsub channels / patterns the client is subscribed to.
With the addition of sharded pubsub, it would be useful to print the number of
keychannels the client is subscribed to as well.
