PR Summary

A previous PR that cleaned up the output ofAssertion to fit withget andset caused the assertion to never actually fail, just return results in the desired format.

The change here is to add a new hidden switch--as-assert so thatdsc knows it's running asAssertion. Then when this is used it checks each test result and if any are NOT in desired state, it returns an error that the assertion failed. Many of the changes is just to pass this parameter to the necessary functions. A helper function is used to potentially recursively look at all theinDesiredState properties.
