[WIP] chore(ray): add configure_logging helper to pass to Ray worker_process_setup_hook

[imran-at-datadog]

Description

This PR adds a helper function to add a JSON-formatting handler to the root logger and clear all other handlers which can be passed to Ray's worker_process_setup_hook on ray.init to configure logging on other libraries of interest such as PyTorch, for example:

import logging

import ddtrace
import ray

# Create a lambda function that wraps configure_logging with arguments
configure_logging_with_args = lambda: ddtrace.contrib.ray.configure_logging(logging.INFO)

# Initialize Ray with the setup hook
ray.init(
    runtime_env={"worker_process_setup_hook": configure_logging_with_args},
    logging_config=ray.LoggingConfig(
        encoding="JSON",
        log_level="INFO",  
        additional_log_standard_attrs=['name']
    )
)

This helper function is NOT applied by default, so the user can decide whether it is appropriate for their specific needs. For example if the user has other tools expecting a specific log format they may not want to apply this.

However, we believe in most cases the user will want to format logs as JSON to enable tracer context injection and correlation with traces in the Dist AI Obs UI.

The encoding="JSON" in logging_config only appear to affect messages directly emitted by the Ray logger - However most interesting messages for practical jobs are usually emitted by the main backend libraries used in the job, such as PyTorch, etc.

Passing this function to worker_process_setup_hook results in it running LATE in the worker setup process, and unlike attempting the same thing in the --tracing-startup-hook (which runs early in the worker process setup) this configuration does not get blown away by Ray or third party libraries attempting something similar. According to the Ray docs, a worker_process_setup_hook is the recommended way to configure logging.

Testing

• Repeat tests

Risks

Minimal, since this is off by default.
