Hide public Form.io API

[andrewsignori-aot]

Form.io API is exposed publicly but it does not need to because SIMS-Api acts as a proxy to retrieve and validate the form definitions.

Acceptance criteria

• [ ] Remove the public access to the form.io API.
• [ ] Ensure that API can access the form.io server to retrieve and validate the form definitions.
• [ ] Adjust the form.io load test to use the load test gateway since the form.io API will no longer be available publicly.
• [ ] Adjust the automatic deployment of FormIO definitions

@ninosamson @sslaws can you please confirm if we can 2x this one?

[sslaws]

Hey @michesmith I'd recommend we keep this in 2 but I think we could remove the form.io load test step and move that out to 2x depending on effort.
