Description

### What happened?

Currently the MemoryMonitor dumps heap if it detects GC thrashing.
However if the JVM ooms all of a sudden it doesn't trigger a heap dump and thus there are not observable even if newly added EnableHeapDumps is set.

The container boot should examine if this option is set and if so configure the jvm when launching to dump heap on oom, see https://www.baeldung.com/java-heap-dump-capture#automatically
