[Telemetry] Implement network_controller_backend new API

This CL implements the methods needed for the network_controller_backend
API, namely:
- Open/Close
- StartReplay/StopReplay

Also retains the old API, whose implementation is temporarily replaced
with wrappers around the new API methods.

Follow up CLs will switch clients to the new API and, eventually, remove
the old deprecated methods when no longer used.

My previous CL was getting a bit out of hand and, because I had to switch that
to catapult anyway, I decided to split it into shorter CLs.

Hopefully these will easier to review and less likely to break things. :)
