Add Pillow for stevedore doc build

As part of setting up gate jobs for stevedore, we have turned on
a doc build gate job. That job is failing because it can't install
Pillow. Nothing else uses Pillow, and it is not a runtime dependency
of stevedore.

 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.
