Micrometer JVM heap pressure provides 2 very useful metrics that we are used to predict service outgage:
- jvm.memory.usage.after.gc used for simple alert like >0.9 and trend alert that detects continius glow of non collectable heap (detects memory leaks)
- jvm.gc.overhead used for simple alert (>0.3) that indicates likely incorrect heap memory settings
This PR enables these metrics by default.

Thanks for the PR. Can you please update the test suite as well?
Yes, sure. I've added a check in one unit test only. Please point me if it needed to update/add more tests.
