Possible roadmap to amphora updates

amphora_roadmap.md

1. page history / pass user to plugins (for specific page updates)
2. break out amphora-fs plugin
3. break out amphora-memoization plugin
4. deprecate lists
   • autocomplete → elasticsearch
   • new page templates api
5. nginx / kong
6. streams!
7. break out amphora-scheduling plugin
8. break out amphora-webhooks plugin
9. renderers terminate request
   • amphora v5.x
   • resolveMedia → renderers
   • streaming renderers
   • remove scheduler
   • remove webhooks
   • remove auth, sessions, route WAF (nginx)

Number 6 can be done piecemeal, focusing on utility functions first and then just calling .toPromise on them. Maybe we could but down sections of the codebase in the same way we handled model.js conversions: Pick a route, pick an action (save, render, etc) and then make it's handler be streamed up until the very last possible point.

Webhooks and scheduling would be breaking changes, so that would be v5.x as well.

Last thing: we still need to underscore routes and update all the appropriate packages/services/provide a DB transition
