Upload session query method compatible with memoryfs python library

[brunoabreu0]

Python's memoryfs library handles reading and writing memory files. The open method from MemoryFS class instantiate a MemoryFile object.

MemoryFile class inherits from io.RawIOBase class, thus it can be passed to the file_object parameter of the create_upload_session_query method.

However, MemoryFile does not implements the method fileno() (used on the line 34, to get file_size), also, the method os.path.basename() (used on the line 35 to get file_name) cannot parse MemoryFS paths.

As a solution to turn create_upload_session_query method compatible, I added 2 optional parameters file_size and file_name, so IO objects (as MemoryFile objects) can provide them from the outside of method.

This solution does not break the current usage of the method.
