Allow setting embedded status feature flag to minimal in tests

We recently added support for minimal embedded status, which is gated
behind the `embedded-status` feature flag. In this change, we support
setting `embedded-status` when running end-to-end tests. It defaults
to "full" because this is the current default value for the flag.
