Public bug reported:
In big clusters having hundreds of nodes, neutron rpc workers could be
consumed by rpc requests so much that they can't process state reports
from agents on time.
That lead to a condition when agents begin to "flap", appear dead and
alive. This in turn causes rescheduling which loads neutron-server even
more, creating self-sustaining loop.
