Java 9 removed support for sun.misc.Cleaner in favor of
java.lang.ref.Cleaner. This change adds a thin abstraction to switch
between Cleaner implementations based on JDK version at runtime

* Improve instantiation of ObjectMappers that require MixIn for redacting password from task logs
* Add comment to clarify fully qualified references of Objects in SQLMetadataStorageActionHandler
The current bytebuffer unmap operations are not compatible with Java 9
and above. This change adapts the code from Apache Kafka to perform the
appropriate unmap operation based on JDK version at runtime.

PR #6902 introduced the ability to use virtual columns for filters, but they
were being omitted from "scan" queries, so filters would refer to a null column
instead of the intended virtual column.
* Update scan query runner factory to accept SpecificSegmentSpec
* nit
* Sorry travis
* Improve logging and fix doc
* Bug fix
* Friendlier error msgs and tests to cover bug
* Address Gian's comments
* Fix doc
* Added tests for empty and null column list
* Style
* Fix checking wrong order (looking at query param when it should be
looking at the null-handled order)
* Add test case for null order
* Fix ScanQueryRunnerTest
* Forbidden APIs fixed
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 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.
