Although I would comment that this won't affect the reactor timeout, as we don't start the reactor timeout process until all the pre checks have fired.  But I'm good with it either way.

> This patch provides a framework for doing pre- and post-test condition checking for an individual test run.  This allows a test to take a snapshot of the state of its Asterisk instances before it executes and compare that against a snapshot of its Asterisk instances after the test executes.  Depending on the test configuration, the test can either pass or fail based on whether or not resources were left uncollected in Asterisk after test execution.

> All pre- and post-test condition objects must inherit from the class TestCondition.  The objects are created dynamically using python reflection and registered as either a pre- or post- check based on the test-config.yaml file for each test.  Post TestConditions can be set to reference the Pre-Test condition object, such that the object is supplied to the post-test object during its evaluation.  This allows the post-test condition object to make its evaluation based on the initial state of Asterisk as captured by the pre-test object.  TestConditions are also allowed to have 'expected failure' states set to them, in case the tests in question are known to fail.

The objects ensure that after a test run, the threads currently active in Asterisk are the same threads that were active prior to the test run.  The voicemail tests were updated to use this as an example.
