Description

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.

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"

Configuration for JitWatch

env.java.opts: "-XX:+UnlockDiagnosticVMOptions -XX:+TraceClassLoading -XX:+LogCompilation -XX:LogFile=${LOG_PREFIX}.jit -XX:+PrintAssembly"
