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 Prepared Statement.
[PreparedStatementTest]
Added some case test of statement-creation methods. [Connection Test]
