redis-cli: Sleep for a while in each cliConnect when we got connect error in cluster mode. (#8884)

There's an infinite loop when redis-cli fails to connect in cluster mode.
This commit adds a 1 second sleep to prevent flooding the console with errors.
It also adds a specific error print in a few places that could have error without printing anything.
