This re-works the way that CLI options are passed through to the analyzer so that they can act as overrides for config options. If not given on the CLI, options will come from a config file. If no file is used then a default value is chosen. Two lists are also populated with tests to include or exclude. These lists are not used for now but will eventually replace the way we select test to run in a future patch to follow.
