Reduce verbosity of ping message

[boldpulse]

Description

I improved the flexibility by reducing the warning level of the KEEPALIVE log message. So when we look at the log output in the k8s examples, there are a lot of ping error messages for KEEPALIVE, but I tracked down the right one and reduced it to a lower log level(Warning) should make that output more readable
