The site ID is not visible in settings form if set via environment variable
Set site ID using the FASTLY_SITE_ID environment variable. The settings form has an empty site ID config field.
Show the ID and disable the form field.
Is this the right approach?
The API token is visible in the form when set via the environment, and it can be edited.
The service ID field id hidden when set via the environment. It cannot be seen in the form.
The three settings / environment variables should probably behave the same way.
The site ID field is disable if it is set using an environment variable.
None.
None.
