Allow passing reservation id to tn order

error_list can be a list

Merge branch 'customer_id_in_order'

* customer_id_in_order:
  Include customer id as CustomerOrderId when ordering number

Include customer id as CustomerOrderId when ordering number

So we can tell who ordered a number in case of issues

Merge branch 'no-more-catapult'

* no-more-catapult:
  Remove catapult import code

Remove catapult import code

Merge branch 'command-object'

* command-object:
  ErrorToSend => FinalStanza
  Since Command#finish causes an error, a then off the end won't work
  Refactor commands to have Command and Command::Execution objects

Refactor commands to have Command and Command::Execution objects

Brings the common elements of all commands together, and threads the most useful
state (such as ability to reply) through automatically using the new EMPromise
fiber trampoline.

Set location (API calls it "SipPeer") on new TN orders

Merge branch 'create-reset-sip-account'

* create-reset-sip-account:
  Create or reset SIP account
  Factor out Catapult connection

Factor out Catapult connection

So that every object which needs to talk to Catapult does not need to know
everthing about it.

Merge branch 'import-to-catapult'

* import-to-catapult:
  Import newly-purchased numbers to Catapult

Import newly-purchased numbers to Catapult

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

Helper to allow ordering phone number from Bandwidth v2

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.
