What you expected to happen:
cli execute with no error, print List operator parameters

How to reproduce it (as minimally and precisely as possible):
Execute: kubectl-kudo package params list --help

Anything else we need to know?:

The reason is -v is a global flag for log level, see below:

Global Flags:
      --home string           location of your KUDO config. (default "/home/xw/.kudo")
      --kubeconfig string     Path to your Kubernetes configuration file. (default "/home/xw/.kube/config")
  -n, --namespace string      Target namespace for the object. (default "default")
      --request-timeout int   Request timeout value, in seconds.  Defaults to 0 (unlimited)
  -v, --v                     log level for V logs

Environment:

• Kubernetes version (use kubectl version):
  Client Version: v1.16.2
  Server Version: v1.15.5
• Kudo version (use kubectl kudo version):
  KUDO Version: version.Info{GitVersion:"0.8.0", GitCommit:"2a585aed", BuildDate:"2019-11-08T16:35:17Z", GoVersion:"go1.13.4", Compiler:"gc", Platform:"linux/amd64"}
• Operator:
• operatorVersion:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

Suggest just remove the short flag -v, keep the long flag --version for setting the specific package version, I send a PR for this.
Welcome opinions, if it is not ok.
