Upstream Issue: https://github.com/kubernetes/kubernetes/issues/77603

Long log lines get corrupted when using '--timestamps' by the Kubelet.

The root cause is that the buffer reads up to a new line. If the line is greater than 4096 bytes and '--timestamps' is turrned on the kubelet will write the timestamp and the partial log line. We will need to refactor the ReadLogs function to allow for a partial line read.
