Log Dir for gc-worker.log is not using same VAR as logs dir for other ranger logs

While trying to use the "ranger_in_docker" script for bringing up ranger services on local, the log dir is set to "var/log/ranger" using the variable ${RANGER_ADMIN_LOG_DIR}.

This path does not get used for gc-worker.log since its hardcoded to use -"Xloggc:${XAPOLICYMGR_EWS_DIR}/logs/gc-worker.log" in the "ranger-admin-services.sh" script.

This causes issues for "gc-worker.log" to not be generated.

While Java8 is fine with this error, when we use Java11, the JVM fails to start.
Hence, raising this JIRA.
