Add NetlifyCMS

[geekyme]

Description

This adds configurations required for NetlifyCMS to work. I limit the scope of CMS edits to just the faq pages. Our new workflow:

• [CHANGED] Content will be edited or created via CMS
• [SAME] Content will be approved or published via Github

See screenshot of the flow

The CMS should be available at the https://taiwangoldcard-cms.netlify.app/admin endpoint, and CMS users are added using netlify identity service. All requested reviewers have already been invited to the instance.

Closes #46

Motivation

As described in https://github.com/taiwangoldcard/website/issues/46, we want to:

• Allow content contributors to write content, but not necessarily access to publish
• Keep the style of raising PRs whenever content writers update something in the CMS

Deployment

There is no change to existing deployment flow for https://taiwangoldcard.com.

I've setup a netlify instance in parallel, which will detect changes on master and build its copy for the CMS. So https://taiwangoldcard-cms.netlify.app/admin is our secret url to access the CMS.

I don't think accessing https://taiwangoldcard.com/admin will work according to this. But if it happens to work then I can get rid of my netlify instance.

Limitations / Risks

Netlify Identify service only allows up to 5 users per website. Therefore we can only allow 5 users into the CMS -

We can have shared account for content editors to work around this.

@geekyme Did you mean to check in the screenshot?

@matrinox thanks for the catch. I've removed it

Sure let me wait a couple of days for @pqvst to give his thoughts.
