Parameterized test cases

[jdduncan]

This is a generalized version of the work to allow running the test suite with multiple adapters. It relates to removing all use of globals in test cases, by providing a dictionary of test parameters.

A test driver can set parameters with jones_test.driver.setParameter(); an individual test case, instantiated from e.g. new SmokeTest(), could retrieve them via test.getParameter().

In a single test run, it should be possible to run a test suite multiple times with different sets of parameters.

A test that requires a parameter (e.g. a test that must have an adapter set) could declare this by calling a method like "usesParameter" or "withParameter":

var t1 = new jones_test.ConcurrentTest("SimpleInsert");
t1.usesParameter("adapter");

Or, fluently:
t1 = new jones_test.ConcurrentTest("SimpleInsert").withParameter("adapter");

The test driver should run non-parameterized tests once.
For parameterized tests, the driver should run them once per supplied parameter value.

A SmokeTest could register a parameter for every test in its suite:

t1 = new SmokeTest();
t1.suite.usesParameter("adapter");
