Includes per-family vCPU quotas (e.g., standardDSv3Family) and total regional vCPU quota.
Use this to check available capacity before deploying VMs.
Cross-reference with VmSizeDto.Family and VmSizeDto.Cores to determine if a deployment will succeed.
Supports filtering, sorting, and pagination. Results are cached server-side for 5 minutes.

Useful filter examples:

• Families with active usage: filter=gt(currentUsage,0)
• Specific family lookup: filter=eq(name,standardDSv3Family)
• Total regional quota: filter=eq(name,cores)
