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

* Fix codes for abnoraml inputs, updated math-expr.md
* Fix assert text
* Fix error messages and refactor codes
* Fix compile error, update sql.md, refactor codes and format tests
* Enhnace the HttpFirehose to work with both insecure URIs and URIs requiring basic authentication
* Improve security of enhanced HttpFirehoseFactory by not logging auth credentials
* Fix checkstyle failure in HttpFirehoseFactory.java
* Update docs and fix TeamCity build with required noinspection
* Indentation cleanup and logic modification for HttpFirehose object stream
* Remove default Empty string password provider in http firehose
* Add JavaDoc for MixIn describing its intended use
* Reverting documentation notation for json code to be inline with rest of doc
* 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.
* Add time taken by query
* Fix time to 2 dp; set state in on state change; hide time taken at first
* Refactored code: defined query result interface; more concise shorthand expression
* Use single quote
