Title: Move network monitoring from xapi to networkd

The monitor thread periodically records statistics and metrics about PIFs and VIFs. This pull request moves the sampling code from xapi (from monitor.ml) to networkd. The reduce the communication overhead, networkd writes the stats to a shared memory file (a file in /dev/shm), for xapi to consume, rather than using the RPC mechanism.
