    Use CephRgwCertificateKeySize, not CephCertificateKeySize, for RGW

    When using key_size_override_unset to choose either CertificateKeySize
    or CephRgwCertificateKeySize, base the setting of the condition
    key_size_override_unset on if CephRgwCertificateKeySize is empty,
    not on if CephCertificateKeySize is empty.
