Bumps ray[default,rllib] from 2.5.0 to 2.8.1.

Release notes

Sourced from ray[default,rllib]'s releases.

Ray-2.8.0

Release Highlights

This release features stability improvements and API clean-ups across the Ray libraries.

  • In Ray Serve, we are deprecating the previously experimental DAG API for deployment graphs. Model composition will be supported through deployment handles providing more flexibility and stability. The previously deprecated Ray Serve 1.x APIs have also been removed. We’ve also added a new Java APIs that aligns with the Ray Serve 2.x APIs. More API changes in the release notes below.
  • In RLlib, we’ve moved 24 algorithms into rllib_contrib (still available within RLlib for Ray 2.8).
  • We’ve added support for PyTorch-compatible input files shuffling for Ray Data. This allows users to randomly shuffle input files for better model training accuracy. This release also features new Ray Data datasources for Databricks and BigQuery.
  • On the Ray Dashboard, we’ve added new metrics for Ray Data in the Metrics tab. This allows users to monitor Ray Data workload including real time metrics of cluster memory, CPU, GPU, output data size, etc. See the doc for more details.
  • Ray Core now supports profiling GPU tasks or actors using Nvidia Nsight. See the documentation for instructions.
  • We fixed 2 critical bugs raised by many kuberay / ML library users, including a child process leak issue from Ray worker that leaks the GPU memory (#40182) and an job page excessive loading time issue when Ray HA cluster restarts a head node (#40742)
  • Python 3.7 support is officially deprecated from Ray.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
