Tailing pod logs with higher log rate fails.

[evilbulgarian]

Description

We notices that on the flatcaros nodes when tailing pods with higher log volume tailing the logs fails. After increasing fs.inotify.max_user_watches seems to alleviate the issue.

Impact

debugging cluster issues is impacted

Environment and steps to reproduce

1. flatcaros stable nodes running busy containers
2. kubectl logs | stern logs should work on busy containers

Expected behavior

stern and logs should work even on busy containers
