New alert type for cronjobs/background scripts monitoring

[quintanilhar]

Hello,

What do you think if we create a new alert type for cronjob/background script monitoring?

The idea is to provide a unique endpoint for each job you want to monitor and after you can make a request call before/after the script run so if it has not run in X time we can generate an alert for that.

Just like this tool: https://cronitor.io

@quintanilhar I'd be willing to accept a PR for this feature. Each Search object has a state_data field that could be used to store this context.
