Introduces a new overridesJsonFile which is consumed by path.resolve(overridesJsonFile).
Usage
Contents of this overrides JSON file can have two possible fields; options and config. These two fields are eventually used by Lighthouse to populate opts and config arguments respectively as illustrated in Using programmatically. The two objects populating this JSON file are merged shallowly with the default config and options.
