Dialogflow: Other availibility zones

[arjan]

Dialogflow (ES) supports multiple availability zones now.
The current generated client is not capable of handling this, as the base URL is hardcoded in the generated Connection module. What would be a solution for this?

If I would program it manually i would add a zone to the opts passed into each function, and from the zone opt the proper Connection would be selected.

So there would exist several different Connection modules, one for each zone, basically four modules:

Current solution is here: botsquad/google_api_dialogflow_fork@1d55a32

Created a new/2 function:

conn = Connection.new("token", zone: "europe-west2")

Let me know if I should create a PR for the Elixir generator.
