Consider integrating Apprise for notification support

[jlowin]

Apprise is a lightweight notification service for Python with many integrations.

A notification task could look as simple as this, while still enabling users to send messages to almost 50 different network (including Slack, email, Twitter, SMS, and arbitrary JSON payloads).

@task
def notify(url, title, body):
    # NOT TESTED
	a = Apprise()
    a.add(url)
    a.notify(title, body)

Because (I believe) Apprise embeds auth in the URL, this would be as easy as returning the URL from an appropriately-configured task OR allowing users to set it via secret.

Bonus points for embedding this in a state handler...

Slack support appears to be based on deprecated webhooks, not apps, though...

@jlowin Hi, i stumbled across this ticket just searching GitHub to see who was using Apprise. The good news is Apprise also supports Slack apps; but the documentation didn't reflect this.

Upon seeing your post, I've since updated it.

Hopefully that helps; let me know if you have any questions!

@caronc awesome! Thanks for the update, I'm excited to work out a first-class Apprise integration for Prefect
