task(auth): Setup route handler for sms recovery phone

[dschom]

Because

• We want to hook up the API endpoints
• We needed at least one end point to test this
• We wanted to be able to setup a recovery phone number

This pull request

• Setups the initialization process for the recovery phone service
• Adds the /recovery-phone/create endpoint
• Adds necessary configuration for recovery phone service / twilio
• Adds unit tests
• Adds integration tests
• Adds necessary glean metrics
• Does a little cleanup:
  • Uses actual RecoveryNumberNotSupportedError in sms.manager
  • Returns a 'failed' status in case something unexpected happens during sms send
  • Publicly exposes recovery-phone.errors and recovery-phone.service

Issue that this pull request solves

Closes: FXA-10354, FXA-10355

For the time being, the integration test added in this PR fails. We need to setup a twilio dev account for our CI or add a twilio emulator.
