Allow configuring Flink's Java options with the logging prefix and log rotation. For example, this allows the following configurations to write {{.jfr}} and {{.jit}} files alongside the existing {{.log}} and {{.out}} files.

{code:language=bash|title=Configuration for Java Flight Recorder}
env.java.opts: "-XX:+UnlockCommercialFeatures -XX:+UnlockDiagnosticVMOptions -XX:+FlightRecorder -XX:+DebugNonSafepoints -XX:FlightRecorderOptions=defaultrecording=true,dumponexit=true,dumponexitpath=${LOG_PREFIX}.jfr"
{code}

{code:language=bash|title=Configuration for JitWatch}
env.java.opts: "-XX:+UnlockDiagnosticVMOptions -XX:+TraceClassLoading -XX:+LogCompilation -XX:LogFile=${LOG_PREFIX}.jit -XX:+PrintAssembly"
{code}
