DRILL-3566: Fix: PreparedStatement.executeQuery() got ClassCastException.
Main:
Restored DrillResultSetImpl(...)'s statement parameter from overly
restrictive DrillStatementImpl to AvaticaStatement and removed caller
cast that was throwing. (Relatedly, adjusted getStatement() and moved
internal casting from statement to connection.)
Added basic test of querying via PreparedStatement. [PreparedStatementTest]
Added some case test of statement-creation methods. [ConnectionTest]

DRILL-3347: VARCHAR ResultSet.getObject returned ...hadoop.io.Text, not
String.
Core fix:
- Fixed {,Nullable}VarCharAccessor's getObject() to return String instead of
value vector's internal org.apache.hadoop.io.Text.
- Updated unit tests (to expect only String now).
[DatabaseMetaDataGetColumnsTest, ResultSetMetaDataTest]
Also Added getObject check in tracing proxy test. [TracingProxyDriverTest]
Changed hard references to Hadoop's Text and JodaTime's Period to strings in
warning check in tracing proxy. [InvocationReporterImpl]
Cleanup:
- Added @Override annotations. [SqlAccessors]
- (Unintentionally) fixed (undetected) missing comma.
[ValueVectorTypes.tdd]
