[11u] RFR: 8221710: [TESTBUG] more configurable parameters for docker testing

[Severin Gehwolf]

Hi,

Please review one additional docker tests backport. A pre-requisite for
JDK-8224165 to bring down which helps verifying JDK-8220672. The JDK 13
patch applies cleanly, but doesn't work without modifications pointed
out below as JDK 11 doesn't have SkippedException (which is a rather
large changeset to bring down)

Bug: https://bugs.openjdk.java.net/browse/JDK-8221710
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8221710/jdk11/01/webrev/
original changeset: http://hg.openjdk.java.net/jdk/jdk/rev/b354ffb03ae4

Testing: Ran docker tests on Linux x86_64

Thoughts?

Thanks,
Severin
