Separate heatbeat intervals for when service is up verses down

🔖 Feature description

I am currently utilizing Uptime Kuma 2.53 through TrueNAS.

Is it possible to configure the heartbeat interval so that when a service is in a UP state, the check interval is less aggressive (e.g. 300 seconds/5 minutes or 600 seconds/10 minutes). However, when a service is in a DOWN state, I would like the checks to be more aggressive (e.g. 120 seconds/2 minutes or 60 seconds/1 minute).

✔️ Solution

Add two heartcheck intervals instead of one.

❓ Alternatives

None.

📝 Additional Context

This will be less "nosey" for external services that I monitor. Too low of a heartcheck interval can be a reason to block my IP address when the service is working as expected.
