* variant: move into internal/attestation * attesation: move aws attesation into subfolder nitrotpm * config: add aws-sev-snp variant * cli: add tf option to enable AWS SNP For now the implementations in aws/nitrotpm and aws/snp are identical. They both contain the aws/nitrotpm impl. A separate commit will add the actual attestation logic.
