feat: health clients (like hw-health) should send health-reports to core with variable frequency

New Feature

How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

As far as I understand, hw-health at the moment sends health reports to core with a fixed frequency. The fixed frequency has a tradeoff

• if sending is too infrequent, there is a delay in signalling problems (e.g. leaks)
• if sending is too frequent, the load on the core api server increases

Feature Description

To achieve a tradeoff, we can implement sending health reports with variable frequency:

• If a health reports would get sent that has the same contents as the last sent health report, the frequency can be reduced. This would only lead to a visibility delay if the core-server was restarted.
• If the health report contains a new alert, the report can be forwarded earlier.
• If the health report contains no alert, the report can be forwarded later

The logic can probably be contain in an extra crate/library, so that it can be reused by multiple components that need to transmit health reports.
