Add a traffic monitor to detect abnormal scenarios. This CL implements a traffic monitor to detect abnormal scenarios on an network connection. The traffic monitor can be conditionally enabled on a device. It starts periodically sampling the receive and transmit byte counts on a enabled device after the device establishes a connection. When it sees that there is outgoing traffic but no incoming traffic for some sampling periods, it invokes a callback to notify such a scenario. BUG=chromium-os:39433 TEST=Built and ran unit tests.
