Shift website deployment to PROD Swarm

[anjackson]

The website is currently deployed on the access server. It should be running from the PROD Swarm.

• [x] Include PyWB 2.6.3 in deployment.
• [x] Deploy to BETA Swarm.
• [x] Run tests against beta.webarchive.org.uk to verify all is working as expected
• [x] Deploy to PROD Swarm.
• [x] Run tests against prod1.n45.wa.bl.uk to verify all is working as expected.
• [x] Set up API proxywebsite.api.wa.bl.uk:80, pointing to prod1:80
• [x] Run tests against website.n45.wa.bl.uk to verify all is working as expected.

The final deployment steps will need to be done together, to make sure everything is consistent. This should also be done early or late in the day to minimise disruption.

• [x] Update public-facing NGINX proxy configuration to match BETA, using website.api.wa.bl.uk:80 as the back-end.
• [x] Run tests against www.webarchive.org.uk to make sure all is well.

Yep, that was all done early this quarter.
