uploadPart method
Saves a part of an object.
Users number object parts themselves and transmit the numbers to Object Storage. The number uniquely identifies the part and determines its position in the general sequence. The number is an integer in the range from 1 to 10,000 inclusive.
If multiple parts with the same number are uploaded, Object Storage saves the last one received.
The size of each part, except the last one, should be at least 5 MB.
For more information, see General procedure for a multipart upload.
