intelliJ inspections cleanup (#9260)
* intelliJ inspections cleanup

- remove redundant escapes
- performance warnings
- access static member via instance reference
- static method declared final
- inner class may be static

Most of these changes are aesthetic, however, they will allow inspections to
be enabled as part of CI checks going forward

The valuable changes in this delta are:
- using StringBuilder instead of string addition in a loop
    indexing-hadoop/.../Utils.java
    processing/.../ByteBufferMinMaxOffsetHeap.java
- Use class variables instead of static variables for parameterized test
    processing/src/.../ScanQueryLimitRowIteratorTest.java

* Add intelliJ inspection warnings as errors to druid profile

* one more static inner class

Use DataSourceAnalysis throughout the query stack. (#9239)
Builds on #9235, using the datasource analysis functionality to replace various ad-hoc
approaches. The most interesting changes are in ClientQuerySegmentWalker (brokers),
ServerManager (historicals), and SinkQuerySegmentWalker (indexing tasks).

Other changes related to improving how we analyze queries:

1) Changes TimelineServerView to return an Optional timeline, which I thought made
   the analysis changes cleaner to implement.
2) Added QueryToolChest#canPerformSubquery, which is now used by query entry points to
   determine whether it is safe to pass a subquery dataSource to the query toolchest.
   Fixes an issue introduced in #5471 where subqueries under non-groupBy-typed queries
   were silently ignored, since neither the query entry point nor the toolchest did
   anything special with them.
3) Removes the QueryPlus.withQuerySegmentSpec method, which was mostly being used in
   error-prone ways (ignoring any potential subqueries, and not verifying that the
   underlying data source is actually a table). Replaces with a new function,
   Queries.withSpecificSegments, that includes sanity checks.

Chi Cao Minh af74acaa85 Address security vulnerabilities CVSS >= 7 (#8980)
* Address security vulnerabilities CVSS >= 7

Update dependencies to address security vulnerabilities with CVSS scores
of 7 or higher. A new Travis CI job is added to prevent new
high/critical security vulnerabilities from being added.

Updated dependencies:
- api-util 1.0.0 -> 1.0.3
- jackson 2.9.10 -> 2.10.1
- kafka 2.1.0 -> 2.1.1
- libthrift 0.10.0 -> 0.13.0
- protobuf 3.2.0 -> 3.11.0

The following high/critical security vulnerabilities are currently
suppressed (so that the new Travis CI job can be added now) and are left
as future work to fix:
- hibernate-validator:5.2.5
- jackson-mapper-asl:1.9.13
- libthrift:0.6.1
- netty:3.10.6
- nimbus-jose-jwt:4.41.1

* Rename EDL1 license file

* Fix inspection errors

Gian Merlino 77297f4e6f GroupBy array-based result rows. (#8196)
* GroupBy array-based result rows.

Fixes #8118; see that proposal for details.

Other than the GroupBy changes, the main other "interesting" classes are:

- ResultRow: The array-based result type.
- BaseQuery: T is no longer required to be Comparable.
- QueryToolChest: Adds "decorateObjectMapper" to enable query-aware serialization
  and deserialization of result rows (necessary due to their positional nature).
- QueryResource: Uses the new decoration functionality.
- DirectDruidClient: Also uses the new decoration functionality.
- QueryMaker (in Druid SQL): Modifications to read ResultRows.

These classes weren't changed, but got some new javadocs:

- BySegmentQueryRunner
- FinalizeResultsQueryRunner
- Query

* Adjustments for TC stuff.
