DRILL-4728: Add support for new metadata fetch APIs

+ Protobuf messages

- GetCatalogsReq -> GetCatalogsResp

- GetSchemasReq -> GetSchemasResp

- GetTablesReq -> GetTablesResp

- GetColumnsReq -> GetColumnsResp

+ Java Drill client changes

+ Server side changes to handle the metadata API calls

- Provide a self contained `Runnable` implementation for each metadata API

that process the requests and sends the response to client

- In `UserWorker` override the `handle` method that takes the `ResponseSender` and

send the response from the `handle` method instead of returning it.

- Add a method for each new API to UserWorker to submit the metadata work.

- Add a method `addNewWork(Runnable runnable)` to `WorkerBee` to submit a generic

`Runnable` to `ExecutorService`.

- Move out couple of methods from `QueryContext` into a separate interface

`SchemaConfigInfoProvider` to enable instantiating Schema trees without the

full `QueryContext`

+ New protobuf messages increased the `jdbc-all.jar` size. Up the limit to 21MB.

DRILL-4704: Fix incorrect query result when decimal is compared with int value

Make sure implicit cast function is provided with the correct precision value

for int/bigint input.

This version of the fix passes the unit test, but may increase the chance of

an overflow error, since the precision is not minimized, and thus it is more

likely to exceed that of the destination decimal. see DRILL-4834.

DRILL-4725: Improvements to InfoSchema RecordGenerator needed for DRILL-4714

1. Add support for pushing the filter on following fields into InfoSchemaRecordGenerator:



2. Pushdown LIKE with ESCAPE. Add test TestInfoSchemaFilterPushDown#testFilterPushdown_LikeWithEscape

3. Add a method visitCatalog() to InfoSchemaRecordGenerator to decide whether to explore the catalog or not

4. Refactor CATALOG_DESCRIPTION and CATALOG_CONNECT as constant strings in InfoSchemaConstants.java

5. Update TestInfoSchemaFilterPushDown#testPartialFilterPushDownWithProject as

we are now pushing the filter on COLUMN_NAME field

6. Cleanup:

Rename RecordGenerator -> InfoSchemaRecordGenerator

Add comments in RecordGenerator

Rename SelectedTable -> InfoSchemaTableType
