* EmitterModule: Throw an error on invalid emitter types.
The current behavior of silently using the "noop" emitter is unhelpful
and makes it difficult to debug config typos.
* Add comments.
* BaseAppenderatorDriver: Fix potentially overeager segment cleanup.
Here is a thing that I think can go wrong:
1. We push some segments, then try to publish them transactionally.
2. The segments are actually published, but the 200 OK response gets
lost (connection dropped, whatever).
3. We try again, and on the second try, the publish fails (because
the transaction baseline start metadata no longer matches).
4. Because the publish failed, we delete the pushed segments.
5. But this is bad, because the publish didn't really fail, it actually
succeeded in step 2.
I haven't seen this in the wild, but thought about it while
reviewing #7537.
This patch also cleans up logging a bit, making it more accurate and
somewhat less chatty.
* Avoid wrapping exceptions when not necessary.
* Java 9 compatible specialized class compilation
We currently use Unsafe.defineClass to compile specialized classes,
which has been removed in Java 9 and above. This change switches to
MethodHandles.Lookup.defineClass at runtime, which provides similar
functionality in newer JDK versions.

* fix checkstyle errors
* rename unsafe -> unsafeutil
* move defineClass method to utility class

This feature allows Calcite's Bindable interpreter to be bolted on
top of Druid queries and table scans. I think it should be removed for
a few reasons:
1. It is not recommended for production anyway, because it generates
unscalable query plans (e.g. it will plan a join into two table scans
and then try to do the entire join in memory on the broker).
2. It doesn't work with Druid-specific SQL functions, like TIME_FLOOR,
REGEXP_EXTRACT, APPROX_COUNT_DISTINCT, etc.
3. It makes the SQL planning code needlessly complicated.
With SQL coming out of experimental status soon, it's a good opportunity
to remove this feature.
