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

tasks.

3. Replaced usage of Guava ImmutableLists with TestBaseViewSupport

helper methods by using standard JDK collections.
