RFR:8189762: [TESTBUG] Create tests for JDK-8146115 container awareness and resource configuration

[Bob Vandette]

Could you try to ask Misha to review these changes (mikhailo.seledtsov at oracle.com <mailto:mikhailo.seledtsov at oracle.com>)
since he wrote these tests?

It would be helpful to have a webrev comparing the JDK11 test sources against yours.

In JDK 10, we are using @requires docker.support.  Is this not possible in JDK8?

There have been a few fixes to the docker tests in JDK 11.  You should make sure to get the
latest versions of these tests.

We have also re-worked some of these tests during the addition of the Container Metrics
API and associated tests in JDK 11 to move out common utility classes.

I try to add the “docker” label to any tests and improvements related to cgroups or docker.
Here’s a query for JDK11 AND Label == docker.
