Review logging for API authentication

[kriswest]

Is your feature request related to a problem? Please describe.
The frequent logging of "Warning: No authentication method enabled for API endpoints." suggests that its a required feature that is improperly configured. My understanding is that the message related to the JWT support for the API and that it is an optional feature. However the message suggests a required feature that is improperly configured.

Describe the solution you'd like
Reduced logging of the warning message (e.g. only on config load) and clarification of the message to make clear if it is an optional or required feature.

@jescalada just had a chat with some confused devs searching docs for answer as to whats wrong with their config. I know the docs releases are behind (not sure why), but is this feature covered anywhere other than the config reference?

@kriswest You're right: this feature is completely optional. I was logging as a way to indicate tell users they probably should secure the API, but having to use an OIDC setup for this might be overkill for some orgs. I'll remove the logging as part of another bugfix PR I'm working on.

As for the documentation for the API auth, it should be present here.

Should be fixed now!
