The old user-facing TrialCheckpoint class has been deprecated in favor of `ray.ml.Checkpoint` and will be removed with this PR.
The main change in this PR is to delete the old `TrialCheckpoint` class and replace remaining API calls (e.g. `checkpoint.local_path`) with the correct AIR equivalents.
One issue that comes up is that with Ray client usage, checkpoint directories are not available on the local node (the client). Thus, we can't construct `Checkpoint` objects easily. (Previously, the TrialCheckpoint object held a reference to the location, even if it is not locally available). There are ongoing discussions on how to resolve this in the future. For now, we print an error when such a checkpoint is requested.
Depends on #25805

Ray SGD v1 has been denoted as a deprecated API for a while. This PR fully deprecates Ray SGD v1. An error will be raised if ray.util.sgd package is attempted to be imported.
Closes#16435
This PR consolidates both #21667 and #21759 (look there for features), but improves on them in the following way:
- [x] we reverted renaming of existing projects `tune`, `rllib`, `train`, `cluster`, `serve`, `raysgd` and `data` so that links won't break. I think my consolidation efforts with the `ray-` prefix were a little overeager in that regard. It's better like this. Only the creation of `ray-core` was a necessity, and some files moved into the `rllib` folder, so that should be relatively benign.
- [x] Additionally, we added Algolia `docsearch`, screenshot below. This is _much_ better than our current search. Caveat: there's a sphinx dependency that needs to be replaced (`sphinx-tabs`) by another, newer one (`sphinx-panels`), as the former prevents loading of the `algolia.js` library. Will follow-up in the next PR (hoping this one doesn't get re-re-re-re-reverted).
* [release] update torch_tune_serve_test to use anyscale connect
* use download_results to download model checkpoint
* clean up code to support both OSS and Anyscale
