Multi-level OpsGenie API Key Override

[osnatashush]

Describe the feature request

I would like to request an enhancement to the OpsGenie integration in Gatus that allows for more granular control over which API key is used for different alerts.
Specifically, the ability to override the OpsGenie API key at the group level and the individual alert level.

Proposed Feature:
Implement a hierarchical override system for OpsGenie API keys:

Proposed Configuration Structure:

alerting:
opsgenie:
api-key: ${DEFAULT_OPSGENIE_API_KEY}
priority: P3
overrides:
- group: groupA
api-key: ${GROUP_A_OPSGENIE_API_KEY}
- group: groupB
api-key: ${GROUP_B_OPSGENIE_API_KEY}

endpoints:

• name: example-endpoint
  group: groupA
  alerts:
  • type: opsgenie
    description: "This alert uses a specific API key"
