Integration with knockknock
Is your feature request related to a problem? Please describe.
Training usually takes time. It would be more efficient to let it run and do something else, then and come back when it's done.
Describe the solution you'd like
Preferably, we would like to have a process that automatically informs us when the process finishes. Fortunately, there is a package, called Knockknock, that we can integrate into pytorch-lightning and it will take care how to send notification to us through our favourite channels, i.e. Slack.
If you're interested, I can take a look on how to implement the feature.
