Do we need the interval functionality built into the runner? As opposed to an external solution (crontab or scheduled pipelines)?

Thanks for the review, @janjakubnanista

Do we need the interval functionality built into the runner? As opposed to an external solution (crontab or scheduled pipelines)?

Good question. Either approach should work.
I slightly prefer this in-code approach since:

1. It works for all deployment avenues (local, CI, k8s)
2. It's the same code/implementation for all deployment avenues
3. I'd rather modify Go

Did you have some concerns? Let me know if you wanted to chat further about it.
