Proposed title of this feature request

Support for AWS GP3 Machine API

What are the nature and description of the request?

In December 2020, AWS introduced new Amazon EBS general purpose volumes (gp3):

In RFE—https://issues.redhat.com/browse/RFE-1521, we were asked to open a new RFE for machine API. Hence, I have opened a new RFE.

Why does the customer need this? (List the business requirements here)

The customer is using AWS as his standard public cloud provider and the new "gp3" volume is more cost-effective than "gp2" ($0.08/GB-month vs. $0.10/GB-month). The customer would like to be able to use the new volumes also for OCP.

General-purpose SSD volumes make it easy and cost-effective for customers to meet the IOPS and throughput requirements for transaction-intensive workloads that they want to run on OCP.

The customer is not looking for support during installation only but also afterward in the Machine API.
