Add peer proto fields for NodeGroupTemplateNodeInfoResponse / NodeGroupAutoscalingOptions

[liggitt]

What type of PR is this?

/kind bug
/kind api-change
/kind cleanup

Follow-up to #8660 that missed a v1.Node and v1.Duration fields which have the same issue with not being reliable proto messages, and not being proto messages at all in 1.35.

What this PR does / why we need it:

Adds peer fields which will continue working with 1.35 Kubernetes libraries (nodeBytes for node and standard proto.Duration fields for durations).

The cluster-autoscaler cloudprovider/externalgrpc NodeGroupTemplateNodeInfoResponse and NodeGroupAutoscalingOptions APIs deprecate the nodeInfo, scaleDownUnneededTime, scaleDownUnreadyTime, MaxNodeProvisionTime fields, in favor of nodeBytes, scaleDownUnneededDuration, scaleDownUnreadyDuration, MaxNodeProvisionDuration fields.
