Failure in provisioning GCP E2/T2A instances

[WoosukKwon]

I tested the provisioning of the GCP VMs which will be added in the new GCP catalog (see their specs in https://cloud.google.com/compute/docs/machine-types):

• M1
• g1-small (0.5 vCPU)
• f1-mirco (0.2 vCPU)
• N2D
• C2
• C2D
• T2D
• T2A (ARM-based VM)
• E2

Among theses, I failed to get on-demand E2, on-demand/spot T2A, and on-demand/spot f1-micro. Here are the error messages:

• On-demand E2 (note that I could get a spot E2 instance though)

We may have to test and document the unsupported machine types.

Nice catch @WoosukKwon! Wdyt about leaving the unsupported VM types out of the catalog for now? This way users can get a nicer "VM type not found/supported" error.

In the future we can also consider adding a CLI that shows all supported VM types by looking into the catalogs.

[WoosukKwon]

@concretevitamin Sounds good. Then I think we can keep E2 and only remove t2a and f1-micro VMs. WDYT?

Sounds good.
