These changes refactor the discovery implementation a bit to improve test coverage and remove duplication of common logic shared with the bundle plugin. Specifically, the downloading logic has been moved into a separate package that is shared by bundle and discovery. Second, test coverage in the discovery implementation is increased from ~15% to ~85%. These changes also include a few functional improvements: - The default decision paths can be updated dynamically - The decision logger can be enabled dynamically - Discovery downloading errors are reported in status updates - Discovery bundle is evaluated with all runtime params - Custom plugins can be created dynamically - Status updates include both discovery and bundle status Signed-off-by: Torin Sandall <torinsandall@gmail.com>
