Summary:
*Stack summary*: this stack adds ability to manage device plugins in the same way as client plugins: install, update, uninstall, enable (star) and disable (unstar) them.
*Diff summary*: changed the way how plugin compatibility with devices is checked from dynamic call to "supportsDevice" to static checks of "supportedDevices" metadata property which make it possible to check compatibility without even downloading plugin from Marketplace.
Changelog: plugin compatibility with devices is now checked according to metadata in property "supportedDevices" in package.json
