WIP Automate creation of Otel collector Service

[aorcholski]

JIRA

Description

Adds Otel collector service reconciler. The service is created if dynakube.spec.telemetryService is enabled.

How can this be tested?

1. unittests
2. install dynakube

spec:
  apiUrl: https://....  
  telemetryService: {}

3. check services

[]$ kubectl -n dynatrace get services

NAME                 TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                                                                     AGE
dynakube-telemetry   ClusterIP   3.....           <none>        4317/TCP,4318/TCP,9411/TCP,14250/TCP,6832/TCP,6831/TCP,14268/TCP,8125/TCP   4m41s

4. check conditions

[]$ kubectl -n dynatrace describe dynakube.dynatrace.com/dynakube

Status:
  ...
  Conditions:
    ...
    Last Transition Time:  2025-01-22T17:01:40Z
    Message:               dynakube-telemetry created
    Reason:                ServiceCreated
    Status:                True
    Type:                  OTELCService

5. disable telemetryService

 kubectl -n dynatrace patch dynakube.dynatrace.com/dynakube --type=json -p="[{'op': 'remove', 'path': '/spec/telemetryService'}]" 

6. check services - dynakube-telemetry service should be deleted
7. check conditions - OTELCService condition should be removed
