PA-2589 - Adjust README.md about requirements

This is a workaround to proper handle service identifier from
python2->python3, as bytes is the preferred data type here [1].

PA-2589 - Remove pipenv files and update documentation

PA-2589 - Update requirements

PA-2589 - Adjust README.md and set requirements

- Python 2.7.16 is the minimal python2 requirement;
- Python 3.8.0 is the recommended python version;
- Pipfile and Pipfile.lock were added for python3 use.

PA-2589 - Do not encode service name while sending message

This is not necessary anymore, as minimal python version is now 2.7.

This avoids the need to import a json library just to deserialize the
received message.
