There's A LOT happening in this commit, so here's an outline: First off, urfave/cli has been removed in favour of spf13/cobra. With this, comes changes to the formatting as well as the help page for Kompose. Upon converting, I noticed a CLI flag was NOT appearing for OpenShift. Specifically, --deploymentconfig. This has been added with a note that says it is OpenShift only. Exit codes have been fixed. If the conversion / down / up fails for any reason, Kompose will exit with Code 1. --verbose as well as --suppress-warnings can now be set at the same time. app_test.go in the cli directory has been moved to pkg/transformer to better reflect the testing coverage. version.go has been removed and converted to it's own CLI command in conjuction with (most) Go software. A new CLI command has been created. kompose version --dab isn't a conventional way for short-form CLI paramters. This has been shortened to -b for bundle. CLI flags consisting of only two/three letters have been removed due to it being unconventional for CLI. For example, --dc was removed in preference for --deploymentconfig --replicas has been added as an option when using kompose down or kompose up. This has been added as previously in app.go the replica amount was hard-coded as 1. Differentiating names have been used for flags. For example, persistent flags use the name Global (ex. GlobalOut). Command-specific flags have their own names (ex. UpOpt). Closes #239 #253
