How was this patch tested?

Ran the demo cluster locally. Tested with flyte-sdk and this script

@env.task
async def spew_logs(duration_sec: int = 300, interval_sec: int = 5) -> str:
    elapsed = 0
    iteration = 0
    while elapsed < duration_sec:
        iteration += 1
        print(f"[{elapsed:>4}s] iteration {iteration} - still running...", flush=True)
        await asyncio.sleep(interval_sec)
        elapsed += interval_sec
    print(f"Done after {elapsed}s ({iteration} iterations)", flush=True)
    return f"completed {iteration} iterations"


if __name__ == "__main__":
    import sys

    config_path = sys.argv[1] if len(sys.argv) > 1 else None
    if config_path:
        from flyte.config import Config

        flyte.init_from_config(Config.auto(config_path))
    else:
        flyte.init_from_config()
    run = flyte.run(spew_logs)
    print(f"Run: {run.name}")
    print(f"URL: {run.url}")
    print("Tailing logs...")
    run.action.show_logs(raw=True)

Verified output worked fine

nit: could we move this file to dataproxy/ instead of adding a new folder at the project root

[katrogan]

done but now run logs service depends on logs service - is that okay? eventually we can rip out the run logs service implementation once the sdk changes are in, so i guess it's temporary

yup
