Matt Ellis 5cfd44c73a Add --json to pulumi config get and pulumi config
This supports using `--json` to get configuration information in a
structured way.

The objects we return have the following schema:

```
{
    name: string;
    value: string?;
    secret: bool;
}
```

In the case of `pulumi config` when --show-secrets is not passed, and
there are secret values, the `value` property of the object for that
configuration value will not be set. This differs from the normal
rendering where we show `[secret]`.
