Run ExecutionTest w/integration test framework

I changed the default local.xml to use 2 NCs with
2 partitions each like AsterixHyracksIntegrationUtil
so that the results will match despite using simple
string compare to determine correctness.

There is also one test in particular (big-object-join)
that I had to add an artificial order by clause to
to deal with different results.

Issues outstanding:
- HDFS in ClusterExecutionIT needs to be thought out
