UI changes and Scope:

<this is based on OCM backend scope, needs to be refined for UI scope needed for this feature>

This ticket is for enabling NVIDIA A100-enabled A2 machine type. For more details refer XCMSTRAT-175. 

• Scope of this ticket: CCS only (both Annual and GCP Marketplace)
• Customers should be able to create clusters with GPU instances as well as add new GPU instances
• The quota rules for Annual and GCP Marketplace will be the same. 
• Externally, no new SKUs should be required. The customers should be able to use existing SKUs/entitlements to use both standard non-GPU and GPU instances with the CCS billing model

Not considering a2-ultragpu-8g as this is not currently listed as supported instance type in OCP 4.14, 4.15 docs
