Use requirements.txt for each producer and consumer

[Okabe-Rintarou-0]

Using requirements.txt can specify the version of a certain module. Pip install will download the newest module by default, but it may be incompatible with the system. Also, we can use requirements.txt in Dockerfile.

Would you please provide me with more info about the python and module version? I'd like to help containerize the producers and consumers. @romain-fontugne

Thanks, yes that would be nice to have a requirement file for each producer/consumer. Feel free to make a PR for that. They should all be working with a recent python 3
