Swap the internal representation of the test configuration from OptionParser.Value to a plain old dict. I want to use a dict so that we can accept multiple sources of test configurations.  Since we are just using a dict, no need to use getattr anymore, just extend the native object dict with the options.

Rename opts to config, for consistency.
