Register a callback object to report when an email or a scheduled task was completed

[robertotru]

This is a feature that should allow to register a listener that can report information related to when an email was sent, if a scheduled task was completed, etc.

Ideally, it should be involve both the scheduler and the email service: to be decided!

Kafka, RabbitMQ, Redis support?
Spring Cloud Task version?

Yeah, something like that. I actually have an open pull request where REDIS is used to ensure persistence. It is taking a way too long for testing, but it introduces a certain level of complexity and I would like to be sure that it works reasonably well.

I think that this will be the next task. I was thinking about something easier, like a service EmailListener that, when registered, is called to notify the listener service that an email or a group of email has been sent.

One may need this to react, for instance, to an AJAX call that has to notify the client that a recover email has been sent.

@miguelsauza Aaaaah! I see that Spring Boot 1.5.x added support for Apache Kafka! That one would be nice to be supported for this feature :)
