Detailed steps to reproduce the problem?

In this file:
https://github.com/mongodb/mongo-python-driver/blame/master/pymongo/uri_parser_shared.py
in row 59, app name is written "appname", while every other field is written in camel case notation, so I think it should be "appName".
Can you verify if this is expected behavior or a bug?

Definition of done: what must be done to consider the task complete?

If the bug is confirmed, change line 59 with "appName"
