Support alarms for upcoming arrivals

Summary:

User request:

I would like to setup an alarm. “Echo setup an alarm 10 minutes before the 249 bus arrives”. I think that’s a killer feature.

Steps to reproduce:

N/A

Expected behavior:

Allow the user to set a reminder to alert them when the bus is arriving

Observed behavior:

N/A

Device:

Amazon Echo

This would also require understanding routeIds and headsigns, which are alphanumeric. Currently we only support understanding city names and stop numbers (numeric only).

We could support adding an alarm for a route similarly to how we're allowing route filters now, which is asking "Do you want to set an alarm for X?", and loop through current routes/arrivals to set the reminder.

From a quick search it still appears as though Alexa Skill Kit doesn't directly support the concept of skill-generated alarms.

We may be able to use the OBA register-alarm-for-arrival-and-departure-at-stop API for this:

This is what iOS is currently using, as native iOS doesn't provide a good reminder feature either.
