Improvements

Allow all config options to also be envVars using subpaths as _ which then get translated to - in viper config
Added filters for cluster and service account
Moved version to only output version nothing else. Removed unneeded else statement
Added semver requirement, and checking. Deploy added global.requiredVersion and global.minimumVersion to the stim.deploy.yaml, so you can enforce versions.
Adding validation to check for no arg for completion cmd
Tab completion functionality for bash and zsh
