Consider renaming the `tracer` logger to improve clarity

[yeikel]

As per the logs: https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/java-rest-low-usage-logging.html#_trace_logs

To enable the "Tracer" logs, one needs to change the log levels of the "tracer" log name such as

<logger name="tracer" level="TRACE" additivity="false">
    <appender-ref ref="your_appender_block_name" />
</logger> 

In my opinion, the name "tracer" was a poor choice because it does not link back to Elasticsearch in any way. The "tracer" term may conflict with other projects as well which may not be desired

I always see myself linking back to https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/java-rest-low-usage-logging.html to explain what this does

Hey @yeikel! The log configuration is something that the java clients inherits from the elasticsearch server code through the RestClient (the low level transport client), so we currently don't have a way of changing it. When we'll stop using the server's RestClient (hopefully soon!) we'll be able to name the logs how we want - accepting suggestions!

Thank you for the context.

I noticed that the issue was closed. Could you clarify what changed?

We merged #974 which adds (in the next major version of the client) a new, alternative implementation of the RestClient where we have changed the name of the tracer logger:

elasticsearch-java/java-client/src/main/java/co/elastic/clients/transport/rest5_client/low_level/RequestLogger.java

Line 46 in 93f0b50

private static final Log tracer = LogFactory.getLog(Request.class);

Is that new major version of the client expected soon?

pretty soon 👀
