Feature request: Data should contain how many mandatory local ssds an instance type has

[StephanDollberg]

It seems like with newer instance types GCP is moving away from optional local SSDs to having a fixed set of SSDs per tier.

Would it be possible to add either the local disk count or disk size to the instance data for the lssd instance types?

I see there is disks and diskssizeGb properties but they seem to related to the max network disks. Further localssd seems to be a boolean and not a count of the number of local ssds.
