Machine costs to include mandatory local SSD costs (e.g. a2+, a3, z3)

Is your feature request related to a problem? Please describe.

Many Google Cloud VM shapes require a quantity of local SSD. For example, a2-ultragpu, a3, z3. The shape costs total appear to not include local ssd amounts. The user may be unaware of this and interpret the data as being inclusive of local SSD pricing.

Describe the solution you'd like Machine shape description should be inclusive of any charges that related to local VM hardware, including local SSD SKUs.

Describe alternatives you've considered Add descriptive test indicating local SSD charges are required but not included (deep link to Storage page if needed.)

Additional context

An example is z3-highmem-88, where the 36TB of local ssd cannot be adjusted (mandatory for shape) and accounts for about 30% of the total shape cost ($9,490.01/month with SSD, vs $6,610.01/month without SSD being the cost the app shows.)
