otlp_ingest_enabled capability support for the AG

[PatrikSteuer]

Is your feature request related to a problem? Please describe.
If an AG & OTEL collector are deployed the same endpoints should be used for both. To simplify the setup the collector could forward otlp signals to the AG otlp endpoint.

Describe the solution you'd like
Provide otlp_ingest_enabled capability so the related AG property can be configured.

Describe alternatives you've considered
Sending logs / trace / metrics directly to the cluster environment API, which increases complexity for maintenance.

FWIW: As a wokaround this can already be achieved via spec.activeGate.customProperties.

E.g.

spec:
  activeGate:
    capabilities:
    - routing
    - kubernetes-monitoring
    customProperties:
      value: |
        [otlp_ingest]
        otlp_ingest_enabled=true
