FORMS-1412 Allow designers to add custom metadata to the form.

[usingtechnology]

Description

To support Row level security/filtering and decoupling CHEFS and external systems, allow form designers to add custom metadata for the form. For example, add an external id.

For flexibility, the form metadata is a JSON blob.

Calls to External APIs will add this JSON as a utf8/base64 encoded string with the header: X-FORM-METADATA. Future revisions will support them specifyin their own header name, but keeping simple for now.
