[jdk13u-dev] RFR: 8250627: Use -XX:+/-UseContainerSupport for enabling/disabling Java container metrics

Fri Nov 27 19:32:10 UTC 2020

I would like to backport 8250627 to 13u for parity with 11u.
The patch doesn't apply cleanly since 13u doesn't have cgroups v2 support (JDK-8231111), reapplied manually.
Tested with container tests, including new one and tier1.
