RFR: 8318730: MonitorVmStartTerminate.java still times out after JDK-8209595 [v4]

[Kevin Walls]

> This issue was hard to reproduce or had stopped happening, but was likely a failure to capture the main arguments from a monitored process, caused by slow startups e.g. -Xcomp.  Recent failures seen in Graal testing are most likely the same issue and increasing ARGS_ATTEMPTS has been seen to resolve it.
> 
> While updating the test, fix the very verbose logging: it doesn't need to log, every second, how many nanos it has waited.
> This has made logs from timeouts hardly usable as they are truncated and may miss critical info.  Also, group the "tunable" constants together.
