This logic was previously performed in a GitHub Actions workflow
using yq.
Since every step should now be performed in Bazel, this now needs to happen here.
The user can choose to supply an intermediate
certificate through the config, like they can
for the root key. If none is supplied,
the KDS is queried for a valid ASK.
With the introduction of SNP-based attestation on AWS
some of the information in the report (MAAToken) is not
applicable to all attestation reports anymore.
Thus, make verify cmd CSP-agnostic and move
CSP-specific logic to internal/verify.
Also make internal/attestation/snp CSP aware.
The unittest was flacky as testcases with valid certs
in the getter property lead to those certs being cached
inside the trust module. Other testcases however,
may want to explicitly use invalid certs. The cache
interferes with this.

* config: move AMD root key to global constant
* attestation: add SNP based attestation for aws
* Always enable SNP, regardless of attestation type.
* Make AWSNitroTPM default again
There exists a bug in AWS SNP implementation where sometimes
a host might not be able to produce valid SNP reports.
Since we have to wait for AWS to fix this we are merging SNP
attestation as opt-in feature.
* 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.
* fetch latest version when older than 2 weeks
* extend hack upload tool to pass an upload date
* Revert "config: disable user-facing version Azure SEV SNP fetch for v2.8 (#1882)"

* Revert "use NewAzureSEVSNPVersionList for type guarantees"

don't allow "latest" value and disable user-facing version fetcher for Azure SEV SNP
