- Secrets are never exposed in plaintext in the Cue tree. `dagger query`
won't dump secrets anymore, Cue errors won't contain them either.
- BuildKit-native secrets support through a new `mount` type. This
ensures secrets will never be part of containerd layers, buildkit
cache and generally speaking will never be saved to disk in plaintext.
- Updated netlify as an example
- Added tests
- Changed the Cue definition of a secret to:
```
@dagger(secret)
id: string
}
```
This is to ensure both that setting the wrong input type on a secret
(e.g. `dagger input text`) will fail, and attempting to misuse the
secret (e.g. interpolating, passing as an env variable, etc) will also
fail properly.
