Sunset pan-domain-node

[mbarton]

The most up to date code for panda authentication is in the main repository itself and published under the Guardian org:

• https://github.com/guardian/pan-domain-authentication/#to-verify-login-in-nodejs
• https://github.com/guardian/pan-domain-authentication/tree/master/pan-domain-node
• npm install --save @guardian/pan-domain-node

There are a family of old NPM modules that have been subsumed into the one above:

• https://github.com/guardian/pan-domain-node
• https://github.com/guardian/pan-domain-public-keys
• https://github.com/guardian/pan-domain-validate-user

This issue tracks any remaining Guardian code that needs updating before sunsetting these library:
