• Package Name: azure.storage.datalake
• Package Version: 12.3.1
• Operating System: Any
• Python Version: 3.5+

Describe the bug
Attempt to create PathProperties with kwargs raises TypeError: object.__init__() takes no parameters
That makes mocking DataLike in test difficult

To Reproduce
Steps to reproduce the behavior:

1. Run python REPL
2. Execute following code

from azure.storage.filedatalake import PathProperties
PathProperties(name="bla")

Result

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/<user>/.pyenv/versions/3.5.7/lib/python3.5/site-packages/azure/storage/filedatalake/_models.py", line 231, in __init__
    **kwargs
TypeError: object.__init__() takes no parameters

Expected behavior
PathProperties object returned
