[BUG] Warning logs about client properties while using Kafka passwordless function

[yiliuTo]

Describe the bug
When using Kafka passwordless connection function, there are warning logs of

2022-09-22 14:50:51.784  WARN 30520 --- [           main] .f.AbstractAzureHttpClientBuilderFactory : The client properties of an http-based client is of type com.azure.spring.cloud.core.properties.client.ClientProperties

To Reproduce
Follow the QuickStart to build an application and run.

Expected behavior
Warning logs should be removed without any breaking changes to users.

Now we directly transport service properties to Azure properties, such as:

    protected AzureProperties getAzureProperties() {
        return this.secretClientProperties;
    }

and then resolve the token credential from the transported AzureProperties, so there might be issues where configured properties like proxy or retry are correct for the service, but might not work for the token credential, which needs to be confirmed.

The current implementation will only reduce the log level, a temporary workaround. This problem will be fixed when #32443 gets resolved.
