### What changes were proposed in this pull request? Introduce JVM monitoring in Celeborn Worker using JVMQuake to enable early detection of memory management issues and facilitate fast failure. ### Why are the changes needed? When facing out-of-control memory management in Celeborn Worker we typically use JVMkill as a remedy by killing the process and generating a heap dump for post-analysis. However, even with jvmkill protection, we may still encounter issues caused by JVM running out of memory, such as repeated execution of Full GC without performing any useful work during the pause time. Since the JVM does not exhaust 100% of resources, JVMkill will not be triggered. Therefore JVMQuake is introduced to provide more granular monitoring of GC behavior, enabling early detection of memory management issues and facilitating fast failure. Refers to the principle of [jvmquake](https://github.com/Netflix-Skunkworks/jvmquake) which is a JVMTI agent that attaches to your JVM and automatically signals and kills it when the program has become unstable. ### Does this PR introduce _any_ user-facing change?
