JDK-8325116: Amend jdk.ContainerConfiguration by swap related value

[MBaesken]

jdk.ContainerInformation event could get amended to report the host total swap values for Linux like was done in
https://bugs.openjdk.org/browse/JDK-8296671 by host total memory.
Two additional fields could be added hostSwapTotal, maybe hostSwapFree;
container free swap space in case we find a good implementation, could also be added to the implementation in os_linux.
