This CL adds a new isolate called telemetry_perf_tests_new. This
is a temporary name, so that we can test it out while keeping the
old isolate name. Eventually, this isolate will probably replace the
existing isolate.

The main difference between this and the current telemetry_perf_tests
is the script it's running, which is named
run_multiple_telemetry_benchmarks_as_googletest.py. As the name
suggests, the script runs multiple telemetry benchmarks, which is the
plan for a single swarming task in the future.
