Gian Merlino 29af9f452a Fix for when Hadoop dataSource inputSpec is specified multiple times. (#5790)
This feature was introduced in #5717 but it didn't work in production
because this magical rewriter code wasn't also modified. Now, it is.

VersionedIntervalTimeline: Optimize construction with heavily populated holders. (#5777)
* VersionedIntervalTimeline: Optimize construction with heavily populated holders.

Each time a segment is "add"ed to a timeline, "isComplete" is called on the holder
that it is added to. "isComplete" is an O(segments per chunk) operation, meaning
that adding N segments to a chunk is an O(N^2) operation. This blows up badly if
we have thousands of segments per chunk.

The patch defers the "isComplete" check until after all segments have been
inserted.

* Fix imports.

Surekha 13c616ba24 'maxBytesInMemory' tuningConfig introduced for ingestion tasks (#5583)
* This commit introduces a new tuning config called 'maxBytesInMemory' for ingestion tasks

Currently a config called 'maxRowsInMemory' is present which affects how much memory gets
used for indexing.If this value is not optimal for your JVM heap size, it could lead
to OutOfMemoryError sometimes. A lower value will lead to frequent persists which might
be bad for query performance and a higher value will limit number of persists but require
more jvm heap space and could lead to OOM.
'maxBytesInMemory' is an attempt to solve this problem. It limits the total number of bytes
kept in memory before persisting.

 * The default value is 1/3(Runtime.maxMemory())
 * To maintain the current behaviour set 'maxBytesInMemory' to -1
 * If both 'maxRowsInMemory' and 'maxBytesInMemory' are present, both of them
   will be respected i.e. the first one to go above threshold will trigger persist

* Fix havingSpec on complex aggregators.

- Uses the technique from #4883 on DimFilterHavingSpec too.
- Also uses Transformers from #4890, necessitating a move of that and other
  related classes from druid-server to druid-processing. They probably make
  more sense there anyway.
- Adds a SQL query test.

Fixes #4957.

Introduce "transformSpec" at ingest-time. (#4890)
* Introduce "transformSpec" at ingest-time.

It accepts a "filter" (standard query filter object) and "transforms" (a
list of objects with "name" and "expression"). These can be used to do
filtering and single-row transforms without need for a separate data
processing job.

The "expression" fields use the same expression language as other
expression-based feature.

* Remove forbidden api.

* Some more changes.

- Add nullable annotation to Firehose.nextRow.
- Add tests for index task, realtime task, kafka task, hadoop mapper,
