Add `--skip-deploy` flag to `up` command
Add `--skip-deploy` flag to `up` command

This change adds `--skip-deploy` flag analogous to `--skip-push`
to the `faas-cli up` command. The requrement for this came from
user experience, as using `build` and `push` together without
`deploy` happens frequently
