catapult_base and telemetry are arguably the same import level since they will
both be in catapult. We should decide on which convention we're using and stick
with it. (It's done both ways int he codebase currently.)

Outside of Catapult, these are all just third-party imports that happen to live
in Catapult. I've grouped them together in the latest patch set, for a start.

 from telemetry import benchmark_runner
