Description hysu 2022-11-14 10:55:00 PST

By default, trying to profile JetStream may sometimes result in the profile being cut off before the test finishes due to file size issues. Support for subtests needs to be added in the run-benchmarks harness, and profiling support should require a subtest to be specified (to avoid the test cutting off). 

Also, JetStream should support signposting to help label generated profiles.
