How to handle timeout for Uploading a blob in Azure Storage using Python SDK?

### Which version of the SDK was used? Please provide the output of `pip freeze`.
azure-storage-blob==12.13.1

### What problem was encountered?
I am trying to upload a blob to Azure Storage using Python SDK but I am unable to manage the timeout. The behavior of all timeout values are same.

```
from azure.storage.blob import BlobServiceClient, ContentSettings
from datetime import datetime

STORAGE_CONNECTION_STRING = ''
container = ''
blobFileName = ''
contentType = ''

def upload_blob(localFilePath):
blob_service_client = BlobServiceClient.from_connection_string(STORAGE_CONNECTION_STRING)
blob_client = blob_service_client.get_blob_client(container=container, blob=blobFileName)
content_setting = ContentSettings(content_type=contentType)
with open(localFilePath, "rb") as data:
blob_client.upload_blob(data, overwrite=True, content_settings=content_setting, timeout=30)

@retry(Exception, tries=5, delay=1)
def uploadImageToAzure(imagePath):
try:
upload_blob(imagePath)
except Exception as ex:
print(f'Exception: {ex}, Type:{type(ex)}, Time:{datetime.now()}')
raise Exception(ex)

print('Successfully Uploaded the File')
return True

uploadImageToAzure(imagePath)
```

To check the behavior of timeout. I just turn off my internet during uploading the blob.

Test Cases:
I just pick the random values of timeout and saw the behavior of the above code

- timeout=1

Start with the BlobClient.upload_blob call and the timeout values shown in the issue, then compare its behavior with the retry wrapper and the ServiceRequestError output. Done means establishing and documenting the expected timeout behavior for failed Azure Storage connections, with a reproducible test or clarified guidance.
