Dry run (command line) mode

[pbochynski]

Description
Enable option to generate kubectl commands instead of executing them directly in the API server. When dry run mode / command line mode is enabled there is a place where all executed commands are pushed in the form kubectl apply / kubectl delete / kubectl patch / etc. User can copy those commands to the clipboard and execute them from the command line or include them in the deployment script.

Reasons
UI is perfect for exploring the ecosystem but for repeatable tasks like installing Kyma modules in the CI/CD pipeline people need command line tools.
