INFO type logging to stderr ; should be stdout

[TiloGit]

Hi,

seems that the operator emits INFO messages to stderr.
stdout seems to be the appropriate place for that.

example:

LogSource:  stderr
{"level":"INFO","ts":"2025-01-02T18:17:11.5370000Z","logger":"controllers.DatadogAgent","msg":"Reconciling DatadogAgent","datadogagent":{"name":"datadog","namespace":"default"}}

Here overview (Azure Insights)

Version:

I think this is coming from the logger defaults in controller runtime: https://github.com/kubernetes-sigs/controller-runtime/blob/1ac370e560b19321af779df0610622c03106ec77/pkg/log/zap/zap.go#L148-L150

I'll add a feature request for this for our backlog
