Interface difference between CloudPath and its children

[jruere]

In class CloudPath, stat is a property.

On all of the class children, stat is a method.

This looks like a mistake.

Thanks @jruere, the property is an error on CloudPath. We'd accept a PR to remove it. stat should be a method in order to follow pathlib: https://docs.python.org/3/library/pathlib.html#pathlib.Path.stat
