Handle Twilio Error Code 30500

[k-macmillan]

User Story - Business Need

30500 is a Twilio internal error, and we should mark the notification as temporary-failure.

• Ticket is understood, and QA has been contacted (if the ticket has a QA label).

User Story(ies)

As a VA Notify client
I want my notification updates to be as accurate as possible
So that I can make informed decisions

Additional Info and Resources

The _evaluate_status method controls this behavior. This error code is not mapped, so it fell to a technical error. Add the mapping below to the twilio client twilio_error_code_map. There are too many Twilio statuses to effectively map, so we have to deal with them as we find them.

New constant for retryable:

    RETRYABLE_STATUS_REASON = 'Retryable - Notification is unable to be processed at this time. Replay the request to VA Notify.'

    '30500': TwilioStatus(30500, NOTIFICATION_TEMPORARY_FAILURE, RETRYABLE_STATUS_REASON),

Acceptance Criteria

• New constant added for retries in constants.py, listed in additional information
• 30500 is added as a temporary-failure status with a message matching the additional information section
• This work is added to the sprint review slide deck (key win bullet point and demo slide)

QA Considerations

• Get an appropriately signed test body from the developer to be able to add this to the lambda testing. then test it.
