Lower minimum memory reservation clamp from 256Mi to 64Mi to support
smaller instance types. Reduce eviction threshold from 10% to 7%.

Mark all Kubelet struct fields optional in values.yaml so existing
Kubernetes CRs without a kubelet block still pass schema validation
while defaults are injected via the template.

Kubelet on worker VMs used to join with empty kubeletExtraArgs, so
allocatable memory equaled guest memory and the OS plus kubelet had
no reservation. Under pressure, Linux OOM killer could terminate
kubelet, taking the node NotReady before graceful pod eviction.
Introduce per-group kubelet reservations with sane defaults:
- system-reserved and kube-reserved memory auto-computed as 5% of
effective guest memory, clamped to [256Mi, 1Gi]
- CPU reserved 100m for each
- eviction-hard memory.available<10% (scales with VM size)
Effective memory is taken from group.resources.memory when set,
otherwise resolved from instanceType via the existing Helm lookup
already used for capacity annotations. Users can override any field
per node group via nodeGroups[*].kubelet.

Running make generate at repo root regenerates the zz_generated.deepcopy.go
files. Key fix: Source.DeepCopyInto in the vmdisk package now handles
the new Disk *SourceDisk pointer field, which was previously missing and
would cause pointer aliasing on deep-copy.
Other generated changes are incidental updates to vminstance (Networks
field added, Subnet renamed to Network) and backups CRD manifests picked
up by controller-gen from the current HEAD.
