Some of these are arbitrary and just syncing for the sake of it, however the
image- and runtime-spec are relevant. Interesting changes:
- runtime spec:
- LinuxRLimit is now POSIXRLimit.
- Specs.Config is now a pointer.
- LinuxResources.DisableOOMKiller moved to
LinuxResources.LinuxMemory.DisableOOMKiller
- image spec:
- Platform.Features is removed (unused here).
