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.
