* Allow plugins to add custom command line flags. Addresses #301
* Reduce dependency over Flags class. This will be deprecated so that adhoc flags can be added without any additional manual configuration
* Fix: Argument 1 to "mock_default_args" of "TestMain" has incompatible type "Namespace"; expected "Mock"
* Reduce Flags class to just the initializer.
* Store list of action dest in FlagParser
* Update to latest code signing recommendations
* Move HttpProtocolHandlerPlugin into separate file
* Dont add subject attributes if not provided by upstream. Also handle subprocess.TimeoutExpired raised during certificate generation. Instead of retries, we simply close the connection on timeout
* Remove plugin specific flag initialization methods for now
* Initialize MacOS Menubar application
* Dashboard plugin at-least needs a shutdown hook to teardown any thread/processes started by dashboard backend plugin
* Add menu bar icon
* Add respective test directories
* Sync test banners
* Move plugin tests under its own package
* Enable daemon for threads, other this wont shutdown cleanly
