instanciation of the ceilometer client fails

[David TARDIVEL]

When I run basic-consolidation tempest test, I have this error:

    Ceilometer client instantiation fixup

    A problem was found during manual integration tests which were failing
    because we couldn't instantiate the ceilometer client when trying to
    execute an action plan using the 'basic_consolidation' strategy.

    This patchset fixes the problem with an update of the related tests
