DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.

* Various fixups.

* Uncomment incorrectly commented lines.

* Move TransformSpecTest to the proper module.

* Add druid.indexer.task.ignoreTimestampSpecForDruidInputSource setting.

After this change, the behavior matches that of hadoop indexing.
(Previously, rows with multiple dimension values would be skipped.)

Chi Cao Minh bab78fc80e Parallel indexing single dim partitions (#8925)
* Parallel indexing single dim partitions

Implements single dimension range partitioning for native parallel batch
indexing as described in #8769. This initial version requires the
druid-datasketches extension to be loaded.

The algorithm has 5 phases that are orchestrated by the supervisor in
`ParallelIndexSupervisorTask#runRangePartitionMultiPhaseParallel()`.
These phases and the main classes involved are described below:

1) In parallel, determine the distribution of dimension values for each
   input source split.

   `PartialDimensionDistributionTask` uses `StringSketch` to generate
   the approximate distribution of dimension values for each input
   source split. If the rows are ungrouped,
   `PartialDimensionDistributionTask.UngroupedRowDimensionValueFilter`
   uses a Bloom filter to skip rows that would be grouped. The final
   distribution is sent back to the supervisor via
   `DimensionDistributionReport`.

2) The range partitions are determined.

   In `ParallelIndexSupervisorTask#determineAllRangePartitions()`, the
   supervisor uses `StringSketchMerger` to merge the individual
   `StringSketch`es created in the preceding phase. The merged sketch is
   then used to create the range partitions.

3) In parallel, generate partial range-partitioned segments.

   `PartialRangeSegmentGenerateTask` uses the range partitions
   determined in the preceding phase and
   `RangePartitionCachingLocalSegmentAllocator` to generate
   `SingleDimensionShardSpec`s.  The partition information is sent back
   to the supervisor via `GeneratedGenericPartitionsReport`.

4) The partial range segments are grouped.

   In `ParallelIndexSupervisorTask#groupGenericPartitionLocationsPerPartition()`,
   the supervisor creates the `PartialGenericSegmentMergeIOConfig`s
   necessary for the next phase.

5) In parallel, merge partial range-partitioned segments.

   `PartialGenericSegmentMergeTask` uses `GenericPartitionLocation` to
   retrieve the partial range-partitioned segments generated earlier and
   then merges and publishes them.
