Feature Request: First seen scheduled tasks

[AndyR]

I'd like to be able to create tasks that will execute when a new system is first seen. These tasks will only need to run once, but should trigger when a system is added to Pulseway. For example, we have some security settings that we are deploying and right now we have to manually execute these tasks on new systems (and try to remember). There should be an option to "Run once" when scheduling tasks.
