[NV-1006] Create webhook parser for Mailjet (email)

[davidsoderberg]

Why

To be able to give better answers why a message was not sent to a subscriber we need to get some info from the provider with a webhook. (deliverability status, rejection status etc).

How

To do this we need to implement these functions inside of the provider:

  getMessageId?: (body: any | any[]) => string[];

  parseEventBody?: (
    body: any | any[],
    identifier: string
  ) => IEmailEventBody | undefined;

The getMessageId needs to return all identifiers that should be the same value as id that is returned from sendMessage with help of this we can connect a webhook to the specific message.

parseEventBody will get the full webhook body and the current identifier that the body should be parsed for. If there is nothing to parse the method should return undefined.

All returns that is not undefined should be an object that is in this format:

status: string;

 date: string;

externalId?: string;

attempts?: number;

response?: string;

// Contains the raw content for message from the provider webhook

row?: string;

Note that statuses for email needs to be value from EmailEventStatusEnum and sms should have a status from SmsEventStatusEnum.

Example of how to do it can be found in SendgridEmailProvider.
