Lucian Petrut afc3a16ce3 Fix os-simple-tenant-usage result order
nova usage-list can return incorrect results, having resources counted
twice. This only occurs when using the 2.40 microversion or later.

This microversion introduced pagination, which doesn't work properly.
Nova API will sort the instances using the tenant id and instance uuid,
but 'os-simple-tenant-usage' will not preserve the order when returning
the results.

For this reason, subsequent API calls made by the client will use the
wrong marker (which is supposed to be the last instance id), ending
up counting the same instances twice.

# API samples heavily uses testscenarios. This allows us to use the
# same tests, with slight variations in configuration to ensure our
# various ways of calling the API are compatible. Testscenarios works
# through the class level ``scenarios`` variable. It is an array of
# tuples where the first value in each tuple is an arbitrary name for
# the scenario (should be unique), and the second item is a dictionary
# of attributes to change in the class for the test.
#
# By default we're running scenarios for 2 situations
#
# - Hitting the default /v2 endpoint with the v2.1 Compatibility stack
#
# - Hitting the default /v2.1 endpoint
#
# Things we need to set:
#
# - api_major_version - what version of the API we should be hitting
#
# - microversion - what API microversion should be used
#
# - _additional_fixtures - any additional fixtures need
#
# NOTE(sdague): if you want to build a test that only tests specific
# microversions, then replace the ``scenarios`` class variable in that
# test class with something like:
#
# [("v2_11", {'api_major_version': 'v2.1', 'microversion': '2.11'})]
