We don't have aiohttp support yet, due to which we have to install without cythonized extension. Similarly, there has been some changes in how dataclasses disallows some mutable arguments to be set as a class property, due to which `hydra.conf` fails to import in 3.11. See python/cpython#29867. For now, I have patched the module and avoid importing as a pytest-plugin. dvc-hdfs/pyarrow is not there yet, we'll usually see a release 2-3 months after official reelase. dvc-hdfs is skipped in 3.11 in extras_requires. `--set-params` will return a nice error message if hydra cannot be imported in 3.11. I decided to only patch that in tests.

The `tensor_properties` field of the `ShardedTensorMetadata` dataclass is a reference to a `TensorProperties` object. However, the field is set to `field(default=TensorProperties())` instead of `field(default_factory=TensorProperties)`. This causes an error when using Python 3.11 or later: ```python ValueError: mutable default <class 'torch.distributed._shard.sharded_tensor.metadata.TensorProperties'> for field tensor_properties is not allowed: use default_factory ``` This change in dataclass behavior was introduced in [bpo-44674: Use unhashability as a proxy for mutability for default dataclass __init__ arguments](python/cpython#29867). The current use of `default` instead of `default_factory` also means that all `ShardedTensorMetadata` objects created without specifying `tensor_properties` will share the same `TensorProperties` object.
