Enhancement: Add Apprise support as a vendor

[comnam90]

Hey guys,

This looks awesome, but it would be great if you included support for Apprise as a notification vendor
This would add out of the box support for many many more providers like Teams, twitter, telegram, etc.

Apprise has python libraries for easy integration

import apprise

# Create an Apprise instance
apobj = apprise.Apprise()

# Add all of the notification services by their server url.
# A sample email notification:
apobj.add('mailto://myuserid:mypass@gmail.com')

# A sample pushbullet notification
apobj.add('pbul://o.gn5kj6nfhv736I7jC3cj3QLRiyhgl98b')

# A sample Microsoft Teams notification
apobj.add('msteams:///T1JJ3T3L2@DEFK543/A1BRTD4JD/TIiajkdnlazkcOXrIdevi7F/')

# Then notify these services any time you desire. The below would
# notify all of the services loaded into our Apprise object.
apobj.notify(
    body='what a great notification service!',
    title='my notification title',
)
