Extracted some functions to public package to reuse them in gateway (#966)
* 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
