Molotov extensions in multi-process

[sreeprasannar]

This sample extension doesn't seem to work when number of processes is more than 1: https://molotov.readthedocs.io/en/stable/extending/

It makes sense because the python dictionary is not mutli-process safe. Any recommendations of how to track metrics across the multiple processes?

Try with multiprocessing.Manager().dict()
