Current behavior

If we want to deploy new service (not upgrade), we have to delete state.vvisp.json.

Expected behavior

If we run vvisp deploy-service -r, system will automatically delete state.vvisp.json.
Also, If you want to re-deploy, run $vvisp deploy-service -r notification will be displayed with Nothing to upgrade notification.

What is the motivation / use case for changing the behavior?

It's annoying to delete state.vvisp.json every time.

Environment

vvisp version: v1.0.3


Environment:
- Node version: 10.15.0
- Operating system: Mac OSX
