Limit max executing time for cron tasks

[fermion2020]

Description of the feature
At times, I've encountered situations where cron tasks became unresponsive, causing numerous processes to run and hang indefinitely, thus consuming significant resources.

I believe implementing a maximum execution time limit for cronjobs using the timeout command is a prudent idea. This measure should prevent any potential issues, provided the timeout duration is reasonable. For instance, setting a timeout of 30 minutes for tasks scheduled every 5 minutes should ensure smooth operation without risking system stability.

Benftits of feature

Having better control of background tasks.

It may be beneficial to try looking into this nextcloud option to see if it would solve your issues: https://docs.nextcloud.com/server/28/admin_manual/configuration_server/background_jobs_configuration.html#parameters

I can build that into an environment variable for future releases, but something about killing a process thats long running repeatedly seems like it could eventually come back and hurt.

Regardless, this will likely end up as a feature in an upcoming base image (alpine/debian) release..
