Enhance deployment/integration documentation

[clemrodriguez]

Hi,

First of all thanks for your work.

Is your feature request related to a problem? Please describe. Yes: I tried to deploy this project as plugin following the README.md, but I didn't succed. No exceptions from Camunda, nor any results (no metrics available).

Describe the solution you'd like Have a clear description of the steps to be done to expose Camunda's Prometheus metrics:

• Build (through mvn)
• Deployment within Camunda
• Endpoints where to find metrics

Additional context We want to be able to scrape Camunda's metrics. We plan to deploy it in a K8S cluster. We would like to use this image either version 7.16 or 7.17: camunda/camunda-bpm-platform:run-7.16.0

In my tests I tried to deploy generated jars (1, 2 or example) into /camunda/configuration/userlib/ but I had no success. Below or docker image: `FROM camunda/camunda-bpm-platform:run-7.16.0

COPY --chown=camunda:camunda temp/digiwf-camunda-prometheus-0.0.1.jar /camunda/configuration/userlib/ COPY --chown=camunda:camunda temp/digiwf-camunda-prometheus-starter-0.0.1.jar /camunda/configuration/userlib/ COPY --chown=camunda:camunda temp/example-0.0.1.jar /camunda/configuration/userlib/

ENTRYPOINT ["/sbin/tini", "--"] CMD ["./camunda.sh"] `

Best regards
