1. Added TPCH queries that execute without exceptions.
2. Implemented an option file execution workflow.  This is mainly for debugging purposes, and is not supported in the run script.  An example of including the parameter for this:
mvn clean test -Dtest=org.apache.drill.test.framework.DrillTests#positiveTests -Dtest.def.sources=tpch_all -Dtest.groups=smoke -Doption.file=/root/open-source-drill-test/testing/framework/resources/switch.q
The file containing the option must come in the form of an absolute path.
3. Fixed a bug that caused empty lists of passing and/or failing tests, or incorrect queries in either of the lists.
