Improve test_load_balancer_basic
This patch introduces multiple improvements of test_load_balancer_basic.
1. Use inetd instead of nc on backends.
Running nc in a while True cycle proved to be ineffective
and unreliable in case of a relatively big number of
requests.
2. Add doc string to NeutronRetriever.
3. Add setUp method and cleanups for resources
as a preparation for adding more tests.
4. Other minor fixes of storing internal values.
