Make New forms API (v4) public

I suggest that HubSpot opens the API to the new forms to the public. Currently, this is restriced and any attempt to modify a new form fails with error.

In our non-profit, we need to be able to programmatically create and modify forms. The new forms are much superior to the legacy ones in terms of UX, but the need to automate our workflow leaves us with no option but using the legacy ones.

Please document our options
- DONE: we have global form events already

- What options can we pass to the form?

- document the difference between standard embed and the advanded/deverloper version of the embed

I am surprised to see this was not there when new form was introduced.
