Feature Request: Support multiple endpoints in ServiceMonitor Helm template

[ramsinghtmdc]

Hi Capsule maintainers 👋,

I have submitted this PR #1646 to address a limitation in the ServiceMonitor Helm template.

Problem

The current template only supports a single endpoint (.endpoint), which makes it difficult to configure multiple Prometheus scrape endpoints such as:

• Default /metrics endpoint
• Liveness/Readiness probes via blackbox-exporter (/healthz and /readyz)
• Custom health checks with different scrape intervals

Solution

This PR updates the ServiceMonitor template to iterate over .endpoints instead of assuming a single endpoint. The changes include:

• Support for multiple endpoints in ServiceMonitor
• Integration with blackbox-exporter probes
• Backward compatibility with single-endpoint setups

Benefits

• Users can now define multiple scrape endpoints in values.yaml
• Blackbox-exporter integration works out-of-the-box
• Existing single-endpoint configurations remain functional

The PR has been tested with both single and multiple endpoints and renders valid ServiceMonitor CRDs.

Kindly review and consider merging this PR 🙏. This enhancement will allow Capsule users to configure Prometheus monitoring more flexibly and robustly.

Thanks for your time and review!
