Expanded Hyperdisk Balanced support for M3 and C3 machine types

## Change **Expanded Hyperdisk Balanced support for M3 and C3 machine types**: The maximum number of Hyperdisk Balanced volumes that you can use with C3 and M3 virtual machines has been increased, as follows: * C3 VMs with 4 or 8 vCPUs now support attaching up to 16 Hyperdisk Balanced volumes. * C3 VMs with 16 or more vCPUs support 32 Hyperdisk Balanced volumes. * M3 virtual machines support up to 32 Hyperdisk Balanced volumes, up from 2\. For more information, see the documentation for [M3](https://cloud.google.com/compute/docs/memory-optimized-machines#m3%5Fdisks) and [C3](https://cloud.google.com/compute/docs/general-purpose-machines#c3%5Fdisks) VMs. ## Feature **Preview**: [General Purpose C4 VM](https://cloud.google.com/compute/docs/general-purpose-machines) instances are now available in Public Preview on the [Intel Emerald Rapids CPU](https://cloud.google.com/compute/docs/cpu-platforms). The C4 machine series offers consistently high performance with up to 192 vCPUs and 1.5 GB of DDR5 memory, and support for [Hyperdisk](https://cloud.google.com/compute/docs/disks/hyperdisks) storage.
