8226575: OperatingSystemMXBean should be made container aware

[kvergizova]

The patch applies cleanly, but it requires some modifications.
The original patch added new methods to OperatingSystemMXBean according to CSR JDK-8228428. Backporting them to 13u is not suitable.
Similar to 11u/8u, existing methods have been changed to return the container values instead.
CSR for 13u is filed: JDK-8255834, it's similar to 11u/8u CSR JDK-8248804.

Tested with tier1 and container tests on Linux and Windows, the only failure is containers/docker/TestMemoryAwareness.java which is fixed by follow-up JDK-8236617, the plan is to push them together.
