Gian Merlino 154b6fbcef SQL: Add "POSITION" function. (#6596)
Also add a "fromIndex" argument to the strpos expression function. There
are some -1 and +1 adjustment terms due to the fact that the strpos
expression behaves like Java indexOf (0-indexed), but the POSITION SQL
function is 1-indexed.

Gian Merlino 9444da5038 SQL: Improved behavior when implicitly casting strings to date/time literals. (#5023)
* SQL: Improved behavior when implicitly casting strings to date/time literals.

- Handle all flavors of ISO8601 and SQL literals.
- Throw errors on other literals instead of silently transforming them to 0.

* Respect timeZone when format is null.

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.

* Fix compile error.

* Fix tests.

* Some more changes.

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

* Fix bad merge.

* Adjust imports.

* Adjust whitespace.

* Make Transform into an interface.

Gian Merlino b20e3038b6 SQL: Upgrade to Calcite 1.14.0, some refactoring of internals. (#4889)
* SQL: Upgrade to Calcite 1.14.0, some refactoring of internals.

This brings benefits:
- Ability to do GROUP BY and ORDER BY with ordinals.
- Ability to support IN filters beyond 19 elements (fixes #4203).

Some refactoring of druid-sql internals:
- Builtin aggregators and operators are implemented as SqlAggregators
  and SqlOperatorConversions rather being special cases. This simplifies
  the Expressions and GroupByRules code, which were becoming complex.
- SqlAggregator implementations are no longer responsible for filtering.

Added new functions:
- Expressions: strpos.
- SQL: TRUNCATE, TRUNC, LENGTH, CHAR_LENGTH, STRLEN, STRPOS, SUBSTR,
  and DATE_TRUNC.

* Add missing @Override annotation.

* Adjustments for forbidden APIs.

* Adjustments for forbidden APIs.

* Disable GROUP BY alias.

* Doc reword.

Gian Merlino 1f2afccdf8 Expressions: Add ExprMacros. (#4365)
* Expressions: Add ExprMacros, which have the same syntax as functions, but
can convert themselves to any kind of Expr at parse-time.

ExprMacroTable is an extension point for adding new ExprMacros. Anything
that might need to parse expressions needs an ExprMacroTable, which can
be injected through Guice.

* Address code review comments.

Bingkun Guo 4914925d65 New extension loading mechanism
1) Remove maven client from downloading extensions at runtime.
2) Provide a way to load Druid extensions and hadoop dependencies through file system.
3) Refactor pull-deps so that it can download extensions into extension directories.
4) Add documents on how to use this new extension loading mechanism.
5) Change the way how Druid tarball is generated. Now all the extensions + hadoop-client 2.3.0
are packaged within the Druid tarball.
