    Tests the following operations in the Quantum API using the REST client for
    Quantum:

        create a network for a tenant

        create a subnet for a tenant
        list tenant's subnets

    v2.0 of the Quantum API is assumed. It is also assumed that the following
    options are defined in the [network] section of etc/tempest.conf:

        tenant_network_cidr with a block of cidr's from which smaller blocks
        can be allocated for tenant networks

        tenant_network_mask_bits with the mask bits to be used to partition the
        block defined by tenant-network_cidr
