[MitaliBhalla]

What type of PR is this?

feature

What this PR does / why we need it?

ROSA HCP supports scale-to-zero functionality. For this to work, AWSMachineTemplate.Status.Capacity fields need to be populated by the CAPA provider.

This PR adds ec2:DescribeInstanceTypes permission to the CAPA controller manager credentials policy (ROSANodePoolManagementPolicy), enabling the controller to query instance type specifications (vCPU, memory, etc.) needed for capacity calculations.

Permission Details:

Field	Value
Permission	ec2:DescribeInstanceTypes
Purpose	Populate AWSMachineTemplate.Status.Capacity for scale-to-zero
Conditions	None - AWS Describe APIs don't support resource-level conditions
Resource	* (required for Describe actions)

Which Jira/Github issue(s) this PR fixes?

Fixes SREP-3410

Special notes for your reviewer:

This permission already exists in other policies in this repo:

• sts_hcp_installer_permission_policy.json
• sts_extended_hcp_support_permission_policy.json (NetworkVerifier)
• openshift_hcp_cloud_network_config_cloud_credentials_permission_policy.json

Pre-checks (if applicable):

• Tested latest changes against a cluster
• Included documentation changes with PR
• If this is a new object that is not intended for the FedRAMP environment - N/A (modification to existing policy)
