Disable option "disable oom killer" if running on cgroups v2

[MrRinkana]

Is there an existing feature request for this?

• [x] I have searched the existing issues before opening this feature request.

Describe the feature you would like to see.

The option --oom-kill-disable is ignored by docker on cgroups v2, so if a node is running on such an OS the option should not be available.

Describe the solution you'd like.

The option could be greyed out, with a short text explaining why its disabled, like: "Disabling OOM killer is not supported on systems using cgroups v2".

Additional context to this request.

One alternative would be to allow over-provisioning RAM to a server, while keeping the {{SERVER_MEMORY}}, resulting in some kind of pseudo-disabled oom killer (allowing start commands to use server memory)
