Make it easier to support Amazon Echo / Alexa chat or other chat-type interview formats

[nonprofittechy]

It would be interesting to extend the SMS-interview style support to different chat platforms. They could include Amazon Alexa, but also Facebook Messenger, Jabber, Slack, etc. Many of these platforms have APIs exposed for integration.

A feature improvement could be to make it easier to add this support in future by generalizing the Twilio integration code to speed up plugin development, even if such other chat platform support doesn't become a core feature of docassemble.

Configuration options would be needed to add API keys.

If anyone is interested in adapting for chat interfaces, take a look at the API feature, which has been added since this issue was created. The chat interface could be developed entirely outside of docassemble's Python code base, as a Zapier app or whatever.
