    Deprecate old keystone session config opts

    In the past, the options ca_certificates_file,
    nova_ca_certificates_file, cinder_ca_certificates_file,
    api_insecure, nova_api_insecure, cinder_api_insecure
    were supplied to instantiate nova, neutron and cinder
    clients. These options have now been subsumed in a more
    generic way into the Keystone session logic as 'cafile'
    and 'insecure'. Deprecate the older options in Stein so
    that we can remove them in a future release.

    This deprecation began many releases ago when we switched
    to using keystone sessions [1]. However, we were still
    overriding the values of "insecure" and "cafile" if provided,
    forcing users to continue using deprecated parameters
    "api_insecure" and "ca_certificates_file". So despite
    this fix originating in the Stein release, it would be
    prudent to backport it to all maintained releases and
    remove support for these older options in/beyond Train
    release (9.0.0).
