How to enable iceberg in Dremio 18

@igorsechyn Sorry for the delay, here you go

prepend the “-Ddremio.debug.sysopt.” to the actual sys option

Couple of examples

DREMIO_JAVA_EXTRA_OPTS="-Ddremio.debug.sysopt.store.plugin.wait_millis=120000"
DREMIO_JAVA_EXTRA_OPTS="-Ddremio.debug.sysopt.exec.preferred.codegenerator=java"
