While working on #17948 I found an issue with our Python API client while making collection creation request with big payloads:

Traceback (most recent call last):

  File "/usr/lib/python3.7/ssl.py", line 911, in read
    return self._sslobj.read(len, buffer)
socket.timeout: The read operation timed out

The collection got created but the client failed to wait for the response (it seems that only waits for around 12 seconds no matter which timeout setting is used).
