KACLS authentication token for PrivilegedUnwrap

Bearer token (JWT: RFC 7516) issued by the identity partner (IdP) to attest a user's identity.

This is only used on PrivilegedUnwrap. During PrivilegedUnwrap, if a KACLS JWT is used in place of an IDP authentication token, the recipient KACLS must first fetch the JWKS of the issuer, then verify the token signature, before checking the claims.
