[telemetry] Add deps command to run_benchmark.
$ tools/perf/run_benchmark deps -z telemetry.zip
is now an alias for
$ tools/telemetry/find_dependencies tools/perf/run_benchmark -z telemetry.zip
Any class that implements the OptparseCommand interface can be run as a standalone script or added to run_benchmark/test_runner :)
BUG=345940, 349109
TEST=Run it.
