By looking at the gate configuration, this currently test the LB in the
scenario where there is a single instance with two fake HTTP servers. If
we do get responses during the _send_requests there is no reason to
believe that there is Neutron at fault here. I attribute this spurious
issue with the fact that 10 attempts is too low a threshold. If we raise
the retries slightly, the test runtime should not increase much; however
if we end up getting stuck with one server, then we can say there's
something wrong with a higher degree of confidence.
