@woodpecker-ci/maintainers I would like to get some feedback in this early state. Please let me know what you think about this implementation.

I added mocks for the woodpecker-go client to add some cli tests. However, injecting mock clients into urfave/cli commands is a bit crappy, or I'm too stupid to find a better solution. If you have a better idea, please let me know, happy to change it.
