    Add support for certificate validation
    
    This spec describes changes that would allow Nova to perform
    certificate validation when verifying Glance image signatures.
    While image signing ensures that image data is obtained
    unmodified from Glance, it does not prevent an attacker from
    uploading and signing a malicious image. The addition of Nova
    API changes allows Nova users to control the certificates
    which are allowed to sign images.
    
    This spec describes work related to image verification. For
    more information, see: https://review.openstack.org/#/c/343654
