@quasiben I have everything in for this PR, please take another look when you can.

Automatic Instantiation of One-Worker-Per-GPU
---------------------------------------------

Using the ``dask-cuda-worker`` or ``LocalCUDACluster`` will automatically launch one worker for each GPU available on the node where that is running, avoiding the need for users to select GPUs in their application and thus reducing code complexity.

Using the ``dask-cuda-worker`` or ``LocalCUDACluster`` will automatically launch one worker for each GPU available on the node from where it was executed, avoiding the need for users to select GPUs in their application and thus reducing code complexity.

Automatic Selection of InfiniBand Device
----------------------------------------

When UCX is activated, Dask-CUDA is also capable of selecting the topologically closest InfiniBand device to each GPU, thus ensuring optimal path and improving performance even further by using Remote Direct Memory Access (RDMA) when available. See the :doc:`UCX <ucx>` page for more details.

Made two small suggestions but otherwise I think looks good!
