Check InitialHeapSize and container memory limits before startup

The server memory is 8 GB
Set the memory upper limit of the Cgroup to 60m

The cgroup create operations:
cgcreate -g memory:foo
cd /sys/fs/cgroup/memory/foo
echo 52428800 > memory.limit_in_bytes
echo 62914560 > memory.memsw.limit_in_bytes


$ cgexec -g memory:foo java -XshowSettings:system --version

$ cgexec -g memory:foo java -Xms60m Main

The program started successfully with InitialHeapSize larger than the memory limit
After running for some time, the program memory exceeds the limit and is killed

By adding -XX:+AlwaysPreTouch, the VM will try to commit 60MB when the heap is initialized to its minimum size, and will be killed immediately by cgroups:

$ cgexec -g memory:foo java -XshowSettings:system -Xms60m -XX:+AlwaysPreTouch -version
