RFR: CODETOOLS-7902904: jcstress: Explicit waits for VM shutdowns [v2]

[Aleksey Shipilev]

> Current TestExecutor code spins in the 100ms-wait loop for re-starting the next epoch of scheduling. This is way too large a wait for -m sanity. Reducing it to 10ms throws the non-sanity runs under the bus. We should instead do explicit waits for VM shutdown, and restart the scheduling then.
