DRILL-7024: Refactor ColumnWriter to simplify type-conversion shim

DRILL-7006 added a type conversion "shim" within the row set framework. Basically, we insert a "shim" column writer that takes data in one form (String, say), and does reader-specific conversions to a target format (INT, say).

The code works fine, but the shim class ends up needing to override a bunch of methods which it then passes along to the base writer. This PR refactors the code so that the conversion shim is simpler.

DRILL-7008: Drillbits: clear stale shutdown hooks

mvn install for Drill project consumed 600MiB (there were 160 shutdown hooks)

DRILL-7007: Use verify method in row set tests

Many of the early RowSet-based tests used the pattern:

new RowSetComparison(expected)


Revise this to use the simplified form:

RowSetUtilities.verify(expected, result);

The original form is retained when tests use additional functionality, such as the ability to perform multiple verifications on the same expected batch.

closes #1624

DRILL-7006: Add type conversion to row writers

Modifies the column metadata and writer abstractions to allow a type conversion "shim" to be specified as part of the schema, then inserted as part of the row set writer. Allows, say, setting an Int or Date from a string, parsing the string to obtain the proper data type to store in the vector.

Type conversion not yet supported in the result set loader: some additional complexity needs to be resolved.

Adds unit tests for this functionality. Refactors some existing tests to remove rough edges.

DRILL-6950: Row set-based scan framework

Adds the "plumbing" that connects the scan operator to the result set loader and the scan projection framework. See the various package-info.java files for the technical datails. Also adds a large number of tests.

This PR does not yet introduce an actual scan operator: that will follow in subsequent PRs.

DRILL-6977: Improve Hive tests configuration

1. HiveTestBase data initialization moved to static block

to be initialized once for all derivatives.

2. Extracted Hive driver and storage plugin management from HiveTestDataGenerator

to HiveTestFixture class. This increased cohesion of generator and

added loose coupling between hive test configuration and data generation


3. Replaced usage of Guava ImmutableLists with TestBaseViewSupport

helper methods by using standard JDK collections.
