What should the feature do: We should tune sysctls related to scylla on the scylla nodes. Ideally we need to keep a list in sync with what's in regular scylla deployment but enforcing that may not be realistic. Also some values may need to be raised as we could run multiple scylla pods per kubernetes node.
What is use case behind this feature: Some sysctls can be set directly on our CR but only those that are namespaced (https://kubernetes.io/docs/tasks/administer-cluster/sysctl-cluster/#setting-sysctls-for-a-pod).
fs.inotify.max_user_instances
is one of the cases that aren't namespaced and scylla needs them https://github.com/scylladb/scylla/issues/7700Additional Information: https://scylladb-users.slack.com/archives/CCC9J41FW/p1628195109003700
