Streaming container logs

Making logs streaming as logging default behavior.

Other option to let the snapshot of the logs as a default behavior and trigger the streaming with a flag. 
e.g. `kubectl log <podName> <containerName> --stream`
 
It should show the important ones - I don't think --follow is important to show if -f works equally well
