1. Proposed title of this feature request

Alert Library for simplified management of infrastructure alerts.

2. What is the nature and description of the request?

Today the "Alert rules" tab (in Observe -> Alerts) is showing in-cluster defined alert rules and if they are firing or not.
However, this requires the alerts to be defined in the platform. And currently a defined alert == active alert.

The proposal is to extend the functionality and allow an admin to toggle an alert between disabled and enabled.

3. Why does the customer need this? (List the business requirements here)

tldr

• Cluster admins want few alerts by default
• Cluster admins do not want to create alert rules with yamls
• Cluster admins do not want to wait for a condition to create an alert
• Workload owners want to opt-in to certain alerts specifically about eh workload health and performance

Alerts are useful if the signal to noise ratio is high.
If too many alerts are firing, then there is low value in alerting.

Thus overall it is desirable to ship with a low number of enabled alerts.
At the same time is it desirable to ship a supplemental list of alerts that are known to be helpful in certain scenarios, but not applicable to all customers.
Customers - admins - should have a simple way to enable or disable alerts that they want to use.

4. List any affected packages or components.
