hence allowing to pass extra specs while creating flavors

nova:
  client:
    enabled: True
    resources:
      v21:
        admin_identity:
          flavor:
            m1.tiny_test:
              ram: 512
              disk: 5
              vcpus: 1
              extra_specs:
                hw:mem_page_size: small
