    Configuration: populate the [trustee] section too

    Sahara have been (mis)using few values from keystone_authtoken to set the
    configuration for trust for a long while. This is not a recommended
    practice as those values are for private use of keystonemiddelware.

    During the queens release a new configuration section (trustee)
    was introduced to collect those parameters:
    https://review.openstack.org/#/c/524936/
    The existing parameters are still read if [trustee] is not available,
    but the behavior is fragile and unsupported, so it is officially deprecated
    in Sahara as well.

    The trustee section is populated from the same values used for
    keyston_authtoken, so the same class is re-used in order to write
    the content of the section.
