[Concourse](https://concourse-ci.org/) resource type to send [Apprise](https://github.com/caronc/apprise) notifications.
Code based on [github.com/mockersf/concourse-slack-notifier](https://github.com/mockersf/concourse-slack-notifier).
Currently, only the [persistent storage solution](https://github.com/caronc/apprise-api#persistent-storage-solution) is supported (because that's what I use).
