    As described.
    
    ## Describe Your Solution ๐Ÿ”ง
    
    G1 garbage collector is supported in Java 8+ and has become  the default 
garbage collector in Java 17+.
    Use G1GC to simplify JVM options example in kyuubi-env for KYUUBI_JAVA_OPTS 
and KYUUBI_BEELINE_OPTS, and for better production deployment usage of higher 
Java version users out of box.
    
    - use G1 for garbage collector
    - Remove CMS and ParNew related options
    - Use UseGCOverheadLimit option
    - Use UseStringDeduplication option for G1GC
    - Reorder options in resources, GC mechanism, GC printing/logging
