- I unified where in file the name of `NotificationProvider.name` is placed
- I made sure that all the providers adhere to the signature of `NotificationProvider.send()`
- I made sure that all the providers use `okMsg` if returning success messages directly from the function.
Here a discussion should be had:
Should this be refactored into a constant of `NotificationProvider`? I could imagine that `NotificationProvider.SENDING_SUCCESSFULL` could be a suitable alternative.
- I made sure all providers have the URL they `POST`/`GET` to be extraced into a variable.
=> refactored this way due to Nelsons suggestion
The text block of a slack notification payload is used for mobile
devices and plain text previews. This change allows slack users to see
the name of the failing service without having to open up Slack to read
the entire message.
