* separate methods * basic refactoring * moved common code to util package to use it in gateway * common check for argo rollouts * made code compilable with latest changes on master * Moved options to separate package and created CommandLineOptions instance that will be in sync with options values. * reverted extra changes * initialize CommandLineOptions with default options in module init * wait for paused at annotation before checking deployment paused * moved things around to fix things * reverted unnecessary changes * reverted rolling_upgrade changes * reverted extra change * additional checks in reloader * refactor: ShouldReloadInternal method. It will be called by Reloader ShouldReload has some additional resource/namespace filter checks which are not needed for Reloader * added test cases * moved config to sharable packae * moved resource selector and label selctor methods * fixed pipeline * removed map.yaml * removed vague comment
