- Props are now namespaced to either a policy or query
- Props on policies need to reference props through `for`
- We will automatically make the `for` references if a pack does
  not define any props but includes queries with props

Examples:
```yaml
policies:
  - uid: example1
    name: Example policy 1
    version: "1.0.0"
    authors:
      - name: Mondoo
        email: hello@mondoo.com
    groups:
      - title: group1
        filters: return true
        queries:
          - uid: variant-1
          - uid: variant-2
          - uid: variant-3
          - uid: variant-4
    props:
      - uid: userHome
        for:
          - uid: home
          - uid: homeDir
        mql: return "ex"

queries:
  - uid: variant-1
    mql: props.home + " on 1"
    props:
      - uid: home
        mql: return "p1"

  - uid: variant-2
    mql: props.home + " on 2"
    props:
      - uid: home
        mql: return "p2"

  - uid: variant-3
    mql: props.homeDir + " on 3"
    props:
      - uid: homeDir
        mql: return "p3"

  - uid: variant-4
    mql: props.user + " is the user"
    props:
      - uid: user
        mql: return "ada"
```

```
go run ./apps/cnspec scan -f props.mql.yaml
```

```
home.+: "ex on 1"
home.+: "ex on 2"
homeDir.+: "ex on 3"
user.+: "ada is the user"
```

```
go run ./apps/cnspec scan -f props.mql.yaml --props userHome="return 'foo'"
```

```
homeDir.+: "foo on 3"
user.+: "ada is the user"
home.+: "foo on 1"
home.+: "foo on 2"
```
