This patch introduces new abstractions and changes the way queries are run via the workload runner. A new class 'Workload' is introduced, which represents the notion of a workload in the performance framework (i.e, A set of query names mapped to query strings). The new workflow is: - run-workload acts as a driver. It accepts user parmaters for which queries to run and their execution strategy. It generates workload objects and passes them to the workload-runner. - The workload runner takes a workload, its execution parameters and generates a set of test vectors over which the workload is run iteratively. - A workload is executed by initialiazing a QueryExecutor for each query being run in a test vector. The workload executor is then responsible for execution and gathering results. - The execution details of every query being executed are are stored and returned to the driver (run-workload).
