Improve o11y onboarding experience by including existing OTEL Collector inside Kibana "Add Data"

[alex-fedotyev]

It would be great to connect observability onboarding with locally deployed OTEL Collector with the Kibana "Add Data" wizard.

---

Step 1 (works well) - Start with local Kibana+ES+Collector:

---

Step 2 - Add Data - Use Local Collector:
Currently offers to install and manage APM server instead of connector to existing Collector:

---

Step 2 - Suggested behavior:

Add Data onboarding -> OpenTelemetry -> Show exposes collector port and protocol, like http://host.docker.internal:4318/ to connect containerized apps, and http://localhost:4318 for apps running locally.

Picked up on this too:

For step 1, we have an open issue:

• Add OTLP endpoints to install success message #73

For step 2, adding the OTLP endpoint automatically to the script and using a config with OTLP exporter for EDOT on edge, the challenge we have here is that the current Kibana image used is the one from self-managed, so any changes we do would apply across the board.

I discussed with @ezimuel bit cloud images are not suitable

We might need some help from Kibana here, the same issue happens for the OpenTelemetry K8s/host onboardings. Kibana's could be extended to detect the OTLP endpoint and use it for the configurations (similarly to Kibana's serverless).
