community[minor]: Add CloudBlobLoader that supports loading data from cloud buckets (#21957)
Thank you for contributing to LangChain!

- [ ] **PR title**: "Add CloudBlobLoader"
  - community: Add CloudBlobLoader

- [ ] **PR message**: Add cloud blob loader
    - **Description:** 
 Langchain provides several approaches to read different file formats:

Specific loaders (`CVSLoader`) or blob-compatible loaders
(`FileSystemBlobLoader`). The only implementation proposed for
BlobLoader is `FileSystemBlobLoader`.
      
Many projects retrieve files from cloud storage. We propose a new
implementation of `BlobLoader` to read files from the three cloud
storage systems. The interface is strictly identical to
`FileSystemBlobLoader`. The only difference is the constructor, which
takes a cloud "url" object such as `s3://my-bucket`, `az://my-bucket`,
or `gs://my-bucket`.
      
By streamlining the process, this novel implementation eliminates the
requirement to pre-download files from cloud storage to local temporary
files (which are seldom removed).
      
The code relies on the
[CloudPathLib](https://cloudpathlib.drivendata.org/stable/) library to
interpret cloud URLs. This has been added as an optional dependency.

```Python
loader = CloudBlobLoader("s3://mybucket/id")
for blob in loader.yield_blobs():
    print(blob)
```

- [X] **Dependencies:** CloudPathLib
- [X] **Twitter handle:** pprados


- [X] **Add tests and docs**: Add unit test, but it's easy to convert to
integration test, with some files in a cloud storage (see
`test_cloud_blob_loader.py`)

- [X] **Lint and test**: Run `make format`, `make lint` and `make test`
from the root of the package(s) you've modified.
