  1. Decrease CPU usage of Prometheus exporter 

    Seems like a thread moving the metrics data into the service exposing
them in the Prometheus format was not constrained with any sleep. This
was causing increased CPU usage of kuryr-cni pods without a  real
reason to do it.

This commit solves that by rewriting the thread to use the common
multiprocessing queue pattern.
