Description

Would it be possible to setup some form of emailing of reports, or an indication that a report was run? This would be good so that management doesn't have to go into Netbox and parse out what they're looking for, and then run the report. I don't think the database would need to be touched unless you wanted to track emails sent.

There will likely be many things people want to do after running a report: sending an email, writing a log, calling a webhook, etc. These are all possible now by overriding the run() method, but it would be more convenient to add a post_run() method which report authors can more easily extend.

Related, here's an example showing how to send email in Django. The configured list of administrators is available at django.conf.settings.ADMINS.

Given there there is consensus that #81 will rely on Django signals, would it also be prudent is put in the effort here to fire signals on report completion?

@lampwins I'll defer the signals work until we have a chance to take a look at the whole project and go through adding signals everywhere they need to be, for both #81 and #1127.
