    Change the default digest for pki/ssl_setup to sha256
    
    The default digest was `default`, which meant that the digest was the
    openssl default which may be sha1 or sha256 or better. Keystone will
    now set the default digest to sha256, which conforms to most security
    policies.
    
    This is for security hardening.

    The `default_message_digest` configuration options now default to
    `sha256` instead of `default`.
