3e96721cd9 8253727: [cgroups v2] Memory and swap limits reported incorrectly 
Account for interface files for swap and memory being reported independently.
The cgroup v1-like value is now reported by adding the memory.max value to
the memory.swap.max value, and memory.current and memory.swap.current
respectively.

ff6843ca48 8253714: [cgroups v2] Soft memory limit incorrectly using memory.high 
The early implementation of cgroups v2 support was done with
crun 0.8 and it contained a bug which set memory.high over
memory.low when --memory-reservation was being used as a CLI
option.

This bug has been fixed in later crun versions, starting with
crun 0.11. Use memory.low in OpenJDK as well.

microseconds, which is read verbatim. Similarly for cgroups v2
all units in 'cpu.max' are in microseconds.
