Summary

• Migrates all quota checks from the deprecated aws-sdk-go v1 to aws-sdk-go-v2 (EC2, ASG, Lambda, ELBv2, IAM, Service Quotas) — context-aware paginators, NewFromConfig clients, and regenerated mocks. Bumps Go to 1.24.
• Sets config.WithRetryMaxAttempts(10) on the shared config. The Service Quotas API has a low request rate limit and the exporter calls ListServiceQuotas once per service, so the v2 standard retryer's default of 3 attempts surfaced TooManyRequestsException during normal scrapes. Raising the ceiling lets the SDK back off through throttling.

Test plan

• go build ./cmd
• go test ./... — all packages pass
• Ran the built binary against us-west-2 with default checks: ~3,410 metrics, no throttling.
• Ran each optional flag individually against us-west-2 and validated the expected metric family appears with no errors/throttling:
  • --enable-vpc-endpoints → *_vpc_endpoints_per_vpc
  • --enable-vpcs-per-region → vpcs_per_region
  • --enable-eips-per-region → eips_per_region
  • --enable-nlbs-per-region → nlbs_per_region
  • --enable-iam-roles-per-account → iam_roles_per_account
  • --enable-iam-policies-per-account → iam_policies_per_account

Pull request overview

This PR migrates the quota/usage checks from aws-sdk-go v1 to aws-sdk-go-v2, updating clients, paginators, and mocks, and bumps the project to Go 1.24 to support the updated SDK/tooling.

Changes:

• Replace v1 AWS service clients/interfaces with v2 NewFromConfig clients and context-aware paginators across EC2/VPC/VPC endpoints/ASG/Lambda/ELBv2/IAM/Service Quotas.
• Regenerate/update mocks and unit tests to use v2 API shapes (types.*) and request signatures (context.Context + options).
• Update build/runtime dependencies: Go 1.24 in go.mod and Docker builder image, plus v2 SDK modules in go.mod/go.sum.
