Allow running background monitoring scripts

[DeltaScratchpad]

Giving the ability to run secondary scripts in the background, which can monitor primary scripts and client states would allow for custom local monitoring/management.

This would be extremely valuable for custom metrics monitoring on a docker/Kubernetes deployment etc.

At it's core, the monitor would need to be able to collect client data such as script crash counts, uptime, login time values etc.
These statistics can then be easily used as external metric guides.

Alternatively the client could send events caused by those state changes and leave statistic processing to the plugin.

This wouldn't be too difficult to do from a technical perspective, just need to work out a way to make it user friendly.
