1. Proposed title of this feature request
Need help to configure alert manager on ocp with specific silence rules so that alerts can be enabled in specific times during the day and disabled in other specific times.

2. What is the nature and description of the request?
Conguration request to silence alerts everyday in specific period

3. Why does the customer need this? (List the business requirements here)
Customer mentioned : We have our own application services running in multiple name spaces and are exposing their metrics which are detected by prometheus on OCP and also we have configured Alert Manager for alerting. Meanwhile, those services are not required to be monitored all the time since they are only functioning during static times (periods) everyday so other than those periods we need to silent any related alerts.

The services that are expecting to run everyday in specific period so that users need to disable monitoring outside those periods.

4. More details :
Seems like it is configurable as per upstream documents :
[1] https://github.com/prometheus/alertmanager/pull/2393
[2] https://prometheus.io/docs/alerting/latest/configuration/#time_interval
Need to check if it is possible to configure in RHOCP 4
