        Description

        With JDK-8245543 more sophisticated parsing of /proc/self/mountinfo will be necessary so as to not incorrectly instantiate a cgroups v2 object on a cgroups v1 system. With a little bit of extra tracking of controller info it should be possible to do away with reading /proc/self/mountinfo twice and pass the read info to where version specific objects are instantiated. With that the Java side would work similar to the hotspot side of the container code.
