Spike: Investigate fetching scale from zero information from AWS API

Currently, the AWS actuator has a static list of instance types embedded in it. This means that as new instance types are added, we have to continually update this list.

Ideally, we could fetch this information from the AWS API as we do in GCP.

DoD:

• Investigate availability of instance memory and CPU capacity as an API on AWS
• Determine if we can use this for the autoscaling scale from zero annotations
• If possible, implement the change.
