RFR: CODETOOLS-7902848: jcstress: remove VM batching support

Tue Mar 16 11:02:23 UTC 2021

jcstress allows running multiple test per VM in order to optimize run times. Unfortunately, this feature gets in the way for reproducibility (multiple test contaminate the VM), error reporting (runner has to guess which test failed), and new features (like controlling the compilers). Thus, it is should go.
