Coralogix API changes and token in headers

[Lyranile]

🐛 Describe the Bug

The prom-api endpoint previously used for querying metrics in Prometheus has been deprecated and replaced by the Metrics API in Coralogix. This change affects users who rely on the old endpoint for their metrics dashboards, alerts, and integrations.

🔄 To Reproduce

Steps to reproduce the behavior:

Go to your existing Prometheus configuration that uses the prom-api endpoint.

Attempt to query metrics using the old URL.

Observe that the queries fail or return no data.

Check the Coralogix documentation for the new Metrics API endpoint.

✅ Expected Behavior

You should be able to successfully query metrics using the new Metrics API endpoint without any disruptions to your dashboards or alerts.

📸 Screenshots

If applicable, add screenshots to help explain your problem.

📝 Additional Context

The prom-api endpoint will be permanently disabled after September 30, 2025. Users must transition to the new Metrics API to avoid disruptions in their monitoring and alerting systems.
