DRILL-6492: Ensure schema / workspace case insensitivity in Drill

1. StoragePluginsRegistryImpl was updated:

a. for backward compatibility at init to convert all existing storage plugins names to lower case, in case of duplicates, to log warning and skip the duplicate.

b. to wrap persistent plugins registry into case insensitive store wrapper (CaseInsensitivePersistentStore) to ensure all given keys are converted into lower case when performing insert, update, delete, search operations.

c. to load system storage plugins dynamically by @SystemStorage annotation.

2. StoragePlugins class was updated to stored storage plugins configs by name in case insensitive map.

3. SchemaUtilities.searchSchemaTree method was updated to convert all schema names into lower case to ensure that are they are matched case insensitively (all schemas are stored in Drill in lower case).

4. FileSystemConfig was updated to store workspaces by name in case insensitive hash map.

5. All plugins schema factories are now extend AbstractSchemaFactory to ensure that given schema name is converted to lower case.

6. New method areTableNamesAreCaseInsensitive was added to AbstractSchema to indicate if schema tables names are case insensitive. By default, false. Schema implementation is responsible for table names case insensitive search in case it supports one. Currently, information_schema, sys and hive do so.

7. System storage plugins (information_schema, sys) were refactored to ensure their schema, table names are case insensitive, also the annotation @SystemPlugin and additional constructor were added to allow dynamically load system plugins at storage plugin registry during init phase.

8. MetadataProvider was updated to concert all schema filter conditions into lower case to ensure schema would be matched case insensitively.

9. ShowSchemasHandler, ShowTablesHandler, DescribeTableHandler were updated to ensure schema / tables names (this depends if schema supports case insensitive table names) would be found case insensitively.

DRILL-6494: Drill Plugins Handler

- Storage Plugins Handler service is used op the Drill start-up stage and it updates storage plugins configs from

storage-plugins-override.conf file. If plugins configs are present in the persistence store - they are updated,

otherwise bootstrap plugins are updated and the result configs are loaded to persistence store. If the enabled

status is absent in the storage-plugins-override.conf file, the last plugin config enabled status persists.

- 'drill.exec.storage.action_on_plugins_override_file' Boot option is added. This is the action, which should be

performed on the storage-plugins-override.conf file after successful updating storage plugins configs.

Possible values are: "none" (default), "rename" and "remove".

- The "NULL" issue with updating Hive plugin config by REST is solved. But clients are still being instantiated for disabled

plugins - DRILL-6412.

- "org.honton.chas.hocon:jackson-dataformat-hocon" library is added for the proper deserializing HOCON conf file

- additional refactoring: "com.typesafe:config" and "org.apache.commons:commons-lang3" are placed into DependencyManagement

block with proper versions; correct properties for metrics in "drill-override-example.conf" are specified

DRILL-6381: (Part 3) Planner and Execution implementation to support Secondary Indexes

  1. Index Planning Rules and Plan generators

    - DbScanToIndexScanRule: Top level physical planning rule that drives index planning for several relational algebra patterns.

- DbScanSortRemovalRule: Physical planning rule for index planning for Sort-based operations.

    - Plan Generators: Covering, Non-Covering and Intersect physical plan generators.

    - Support planning with functional indexes such as CAST functions.

    - Enhance PlannerSettings with several configuration options for indexes.

  2. Index Selection and Statistics

    - An IndexSelector that support cost-based index selection of covering and non-covering indexes using statistics and collation properties.

    - Costing of index intersection for comparison with single-index plans.

  3. Planning and execution operators

    - Support RangePartitioning physical operator during query planning and execution.

    - Support RowKeyJoin physical operator during query planning and execution.

    - HashTable and HashJoin changes to support RowKeyJoin and Index Intersection.

    - Enhance Materializer to keep track of subscan association with a particular rowkey join.

  4. Index Planning utilities

    - Utility classes to perform RexNode analysis, including conversion to and from SchemaPath.

    - Utility class to analyze filter condition and an input collation to determine output collation.

    - Helper classes to maintain index contexts for logical and physical planning phase.

    - IndexPlanUtils utility class for various helper methods.

  5. Miscellaneous

    - Separate physical rel for DirectScan.

    - Modify LimitExchangeTranspose rule to handle SingleMergeExchange.

- MD-3880: Return correct status from RangePartitionRecordBatch setupNewSchema
