Ensure Kernel Param settings work across OS's

We've documented recommended Kernel Params for host systems here:

https://docs.couchbase.com/operator/current/best-practices.html#kernel-parameters

However, these commands do not apply across every OS, for instance in Ubuntu the result is:

 sysctl -w mm.transparent_hugepage.enabled=never

sysctl: cannot stat /proc/sys/mm/transparent_hugepage/enabled: No such file or directory 

sysctl is ideal, but we may need to include an example of mounting the filesystem to the DaemonSet to apply kernel params.
