The endpoints added in #6272 were missing authorization checks. This patch removes the bulk
methods from SupervisorManager, and instead has SupervisorResource run the full list through
filterAuthorizedSupervisorIds before calling resume/suspend/terminate one by one.
Make static imports forbidden in tests and remove all occurrences to be
consistent with the non-test code.

Assert.assertEquals() were flipped)

This includes the router, overlord, middleManager, and coordinator.
Does the following things:
- Loads LookupSerdeModule on MM, overlord, and coordinator.
- Adds LookupExprMacro to LookupSerdeModule, which allows these node
types to understand that the 'lookup' function exists.
- Adds a test to make sure that LookupSerdeModule works for virtual
columns, filters, transforms, and dimension specs.
This is implementing the technique discussed on these two issues:
- https://github.com/apache/incubator-druid/issues/7724#issuecomment-494723333
- https://github.com/apache/incubator-druid/pull/7082#discussion_r264888771
* Add checkstyle for "Local variable names shouldn't start with capital"
* Adjust some local variables to constants
* Replace StringUtils.LINE_SEPARATOR with System.lineSeparator()
* fix lookup editor to use lookup tiers instead of historical tiers
* use default tier if empty response, fix if configured lookups is null
* fixes
* fix typo
* Bump Checkstyle to 8.20
Moderate severity vulnerability that affects:
com.puppycrawl.tools:checkstyle
Checkstyle prior to 8.18 loads external DTDs by default,
which can potentially lead to denial of service attacks
or the leaking of confidential information.
Affected versions: < 8.18
* Oops, missed one
* Oops, missed a few
* Set direct memory if unable to detect JVM config
Java 9 and above prevents us from detecting the maximum available direct
memory.
This change adds a fallback method to use at most 25% of maximum heap
size, which should be a reasonable default.
Unless -XX:MaxDirectMemorySize is set, recent JVMs will default maximum
direct memory to match the maximum heap size, so this should work out of
the box in most cases. For completeness we print instructions in the log
to explain how to adjust settings if necessary.
* skip test rather than succeeding
* reword log message

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.

Removes the coordinator sanity check that prevents it from dropping all
segments. It's useful to get rid of this, since the behavior is
unintuitive for dev/testing clusters where users might regularly want
to drop all their data to get back to a clean slate.
But the sanity check was there for a reason: to prevent a race condition
where the coordinator might drop all segments if it ran before the
first metadata store poll finished. This patch addresses that concern
differently, by allowing methods in MetadataSegmentManager to return
null if a poll has not happened yet, and canceling coordinator runs
in that case.
This patch also makes the "dataSources" reference in
SQLMetadataSegmentManager volatile. I'm not sure why it wasn't volatile
before, but it seems necessary to me: it's not final, and it's dereferenced
from multiple threads without synchronization.

* fix indentation
* unused import

* refactor some stuff into processing module, split up LookupModule.java classes into their own files
* Fix two issues with Coordinator -> Overlord communication.
1) ClientCompactQuery needs to recognize the potential for 'intervals'
to be set instead of 'segments'. The lack of this led to a
NullPointerException on DruidCoordinatorSegmentCompactor.java:102.
2) In two locations (DruidCoordinatorSegmentCompactor,
DruidCoordinatorCleanupPendingSegments) tasks were being retrieved
using waiting/pending/running tasks in the wrong order: by checking
'running' first and then 'pending', tasks could be missed if they
moved from 'pending' to 'running' in between the two calls. Replaced
these methods with calls to 'getActiveTasks', a new method that does
the calls in the right order.
* Remove unused import.
* Make IngestSegmentFirehoseFactory splittable for parallel ingestion
