Add an integration test to verify if skaffold updates the survey prompt.

We need an integration test where
1. Skaffold config is empty
2. Run skaffold dev/deploy/run for the first time
3. Make sure the skaffold user survey prompt is shown
4. the survey prompt shown config is updated in the config.

Note: All integration tests share the same global config file. In order to isolate this test, we should create a distinct path for the global config using `-c` flag.
