pyMongo 4.0.1 deprecated methods

[bbgrk]

Expected Behavior

Authentication and Eve working as normal.

Actual Behavior

Authentication (and other things) fail due to deprecated functions in /eve/io/mongo/flask_pymongo.py (and maybe in more files?)
pyMongo defaults to 4.0.1 version.

Environment

• Python version: Python 3.8.10
• Eve version: 1.1.5

Workaround

Use older version of pyMongo. :(

pip3 install pyMongo==3.12.3

duplicate of #1461

[nicolaiarocci]

PS: PyMongo 4 drops support for Python 2. We first have to drop py2 too.

[nicolaiarocci]

Support for pymongo 4+ is now available on master branch. Would be nice if you folks could test it a little bit.
