[jdk17u-dev] RFR: 8320687: sun.jvmstat.monitor.MonitoredHost.getMonitoredHost() throws unexpected exceptions when invoked concurrently [v2]

[Paul Hohensee]

> Backport for parity with Oracle 17.0.16. Clean except for copyright date in MonitoredHost.java, and replacement of try-with-resources in new test with try-catch because ExecutorService does not implement AutoClosable in 17u. New test passes, as well as the existing tests under test/jdk/sun/jvmstat/monitor.
