Since we still use Catapult ("v1") for voice application, we need to import all
numbers there and set their applicationId to match.

Adds the settings to redis that jmp-fwdcalls will use to route inbound calls.
Not done by the sgx registration even though fwdcalls is currently a plug-over,
and of course won't be once fwdcalls dies so do it here.

Assuming credit card payment works, you can now activate a new account by paying
with one.

This is what should know about things like the customer id -> jid mapping, etc.

em-synchrony monkeypatches em-http when loaded. The old functionality is still
present, but under different method names.

Uses their gem which uses Faraday. Set Faraday to em-synchrony so their gem is
now using EventMachine but still sync so their code will work unchanged.  Wrap
all uses of the gem in EM.promise_fiber to get a promise back out of that.

Implement a poll helper that can wait until a new order is complete at Bandwidth
before continuing.  They support an HTTP callback method, but only global on
account? This is much easier to work with in our context.

Instead of a hard-coded case statement.

Bills their balance for the cost of one month of plan.
Activates the plan by insert into plan_log, unless already active in which case
extends current plan by one month.

This helper spins up a fiber and returns an unresolved EMPromise, then runs the
passed-in block inside the fiber and fulfills the promise with the result of the
block. Because nothing is looking for the Fiber to return it is free to act as a
trampoline for EMPromise#sync and other fiber-sync-style code that does not
block the EM reactor.

This step, if chosen, directs the user to the jmp-pay webapp to add a credit
card.  It includes an OOB element for use by user agents that can handle
that (possibly for webview embed, etc) with a note-based fallback as per XEP.
Once the user chooses "next" the code checks if they have actually added a card,
and if so continues to a yet-unimplemented step and if not repeats the
instruction to go to the web app.

This result variable got renamed to registered

* register-command-first-pass:
  Add sourcehut CI
  Add Rakefile to run all tests
  Initial registration flow for Bitcoin
  Registrations that start on the web will have a tel selected already
  Helpers for doing Electrum RPC
  Add helper to fetch current BTC sell prices
  Allow skipping tests without being caught in pry

This is the Bitcoin "happy path" where there is already a tel and a customer_id.
Gets all the way to generating a BTC address for payment and quoting an amount.
Stubs out flows for credit card and activation code as well, but does not
implement those flows.

TBD: after bitcoin payment comes in and jmp-pay activates the account, we should
come back here to actually buy the number, select a new one if no longer
available, etc.

So, manage any already-known tel selections and allow registration to use them
right away.  In the future this will fall back to letting the user search for a
tel over XMPP, but that is not implemented here.

Scrapes the sell price for Bitcoin from canadianbitcoins.com
USD price is done by converting this CAD sell price to USD via openexchangerates

Rubocop clean. Good test coverage of helper objects.

Look up the user's plan to find out what currency to charge them in.

We'd like to actually get the money, not just be allowed to.

Supports registering with backend SGX via basic iq:register.

Does not support data forms version with nice labels.

Does not verify billing or anything else yet, just unconditionally registers the user.
