Roman Leventov af93a8d189 Sequences refactorings and removed unused code (part of #3798) (#3693)
* Removing unused code from io.druid.java.util.common.guava package; fix #3563 (more consistent and paranoiac resource handing in Sequences subsystem); Add Sequences.wrap() for DRY in MetricsEmittingQueryRunner, CPUTimeMetricQueryRunner and SpecificSegmentQueryRunner; Catch MissingSegmentsException in SpecificSegmentQueryRunner's yielder.next() method (follow up on #3617)

* Make Sequences.withEffect() execute the effect if the wrapped sequence throws exception from close()

* Fix strange code in MetricsEmittingQueryRunner

* Add comment on why YieldingSequenceBase is used in Sequences.withEffect()

* Use Closer in OrderedMergeSequence and MergeSequence to close multiple yielders

Gian Merlino d51f5e058d SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators. (#3852)
* SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators.

Switched from CalciteConnection to Planner, bringing benefits:

- CalciteConnection's JDBC interface no longer sits between the SQL server
  (HTTP/Avatica) and Druid's query layer. Instead, the SQL servers can use
  Druid Sequence objects directly, reducing overhead in the query return path.

- Implemented our own Planner-based Avatica Meta, letting us control
  connection timeouts and connection / statement limits. The previous
  CalciteConnection-based implementation didn't have any limits or timeouts.

- The Planner interface lets us override the operator table, opening up
  SQL language extensions. This patch includes two: APPROX_COUNT_DISTINCT
  in core, and a QUANTILE aggregator in the druid-histogram extension.

Also:

- Added INFORMATION_SCHEMA metadata schema.

- Added tests for Unicode literals and escapes.

* Verify statement is actually open before closing it.

* More detailed INFORMATION_SCHEMA docs.

Gian Merlino 657e4512d2 Checkstyle checks for AvoidStaticImport, UnusedImports. (#3660)
Excludes tests from AvoidStaticImport, since those are used often there and
I didn't want to make this changeset too large. Production code use was minimal
and I switched those to non-static imports.
