Add basic setup for sending frames via CAN Bus and Ethernet between three processes (chassis, powertrain, body)

See merge request !3

Temporarily changed Scapy SocketCAN implementation to Python-CAN for easier testing, added enum for frame sending frequencies and made Chassis ECU process generic in order to reuse it for the other vehicle components

Started working on the Process class which is spawned for every ECU in our setup, added a basic Thread class for periodic sending of CAN Frames at different time intervals, refactor parts of code (splitting code into separate files, renaming some of the existing functions and files)

Write PASTA1.0 CAN specifications (frame id, source and target) - source: https://github.com/pasta-auto/PASTA1.0/blob/master/doc/PASTA1.0%20CAN-ID%20List%20v1.0E.pdf

Add scapy installation in both images, together with python3 and pip

See merge request !2

Include docker-compose and container for testing Ethernet traffic

See merge request !1

Update setup to include ethernet container; Add docker-compose with local docker images for the moment

Add Dockerfile for basic container which uses can-utils in order to generate random traffic on a virtual interface
