Warning when ExternalName service loading is enabled

[morremeyer]

Welcome!

• [X] Yes, I've searched similar issues on GitHub and didn't find any.
• [X] Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you do?

Start traefik v3.0.0 with the option

--providers.kubernetescrd.allowExternalNameServices=true

I expected this to not have any effects besides allowing the use of ExternalName services.

What did you see instead?

There is a log with level warning about ExternalName services being enabled.

2024-05-02T10:04:22Z WRN ExternalName service loading is enabled, please ensure that this is expected (see AllowExternalNameServices option) providerName=kubernetescrd

Since ExternalName service loading is enabled because I explicitly configured it, I expect this to not print a log message of level warning, at most the level should be INFO in my opinion.

I'd expect a warning level log message to tell me about something that is wrong, not about me having configured an option.

What version of Traefik are you using?

v3.0.0

What is your environment & configuration?
