text: Title: [GCP][Disk] Google Cloud Hyperdisk support
  Body: It appears that the `ultra` disk which maps to `pd-extreme` does not work with `A3 / A2 / G2` gpu machine types in GCP, so it cannot be used for accelerated ml serving workloads (`H200 / H100 / A100 / L4`)
  
  They support something called `hyperdisk` instead, but it also varies based on instance type with `hyperdisk-ml` having the broadest support:
  
  | instance | disk support | ref |
  |-|-|-|
  |`a3 mega, a3 high, a3 edge`| `hyperdisk-ml, hyperdisk-balanced, hyperdisk-extreme, hyperdisk-throughput, pd-ssd, pd-balanced` | https://cloud.google.com/compute/docs/accelerator-optimized-machines#a3-disks|
  |`a3 ultra`| `hyperdisk-balanced, hyperdisk-extreme`| https://cloud.google.com/compute/docs/accelerator-optimized-machines#a3-disks |
  |`a2`|`hyperdisk-ml, pd-ssd, pd-standard, pd-balanced`| https://cloud.google.com/compute/docs/accelerator-optimized-machines#a2-disks |
  |`g2`|`hyperdisk-ml, hyperdisk-throughput, pd-ssd, pd-balanced`| https://cloud.google.com/compute/docs/accelerator-optimized-machines#g2-disks |
  
  Pricing looks similar to `pd-extreme`: https://cloud.google.com/compute/disks-image-pricing?hl=en#tg1-t0
  
  Is this something that can be added?
