[tests] Fix test retry and allow local token (#3940)

This PR updates the way we run integration tests (the ones that create test deployments) so that it will be less likely to fail. 

A couple side effects to this PR:

- To run the tests locally, you must set `NOW_TOKEN` env var (can be found in `~/.now/auth.json`).
- PRs from forked repos won't run tests because they now rely on a secret in GH Actions.
- A couple alias tests that require certs need to be disabled because they will fail.
