Review Comment:
When they're made conventional Maven exclusions then they act transitively
resulting in size savings. They also make the mvn depedency:tree tool more
useful.
> Fix Hadoop 2 and Netty lib exclusions, REST mem limiter disabled by default
> ---------------------------------------------------------------------------
>
> Key: DRILL-8268
> URL: https://issues.apache.org/jira/browse/DRILL-8268
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.20.1
> Reporter: James Turton
> Assignee: James Turton
> Priority: Major
> Fix For: 1.20.2
>
>
> # New exclusions of reload4j, slf4j-reload4j are required in the Hadoop 2
> profile, probably due to the upgrade of Hadoop from 2.10.1 to 2.10.2.
> # We remove the netty-all metapackage which entered the dependency tree with
> the change introducing the Netty bom bringing many uneeded libs with it.
> # The heap memory usage limiting logic in the REST server becomes disabled
> by default since REST query results are streamed these days. This change aims
> to let the Java GC now do its job without interference and if that results in
> OOM under a constant load then there is good evidence for a heap leak which
> must be tracked down and completely resolved anyway, not mitigated or "swept
> under a rug".
