    Redact x-subject-token from response headers
    
    When you invoke any OpenStack API of any of the OpenStack services
    e.g. glance, neutron, cinder, heat, ceilometer, nova, keystone
    then it logs readable x-subject-token at the debug log level in the
    respective log files.
    
    Simply redacting the x-subject-token in keystone client response header
    before logging it.
