[FEAT]: Support MQTT

[w4bremer]

Description

MQTT will be one of our main IPCs.
Therefore we need to add support for it to the python template.
The implementation needs to be compatible with our Qt and C++ implementations.
It should follow our current mapping v0.1

This task can be split in sub tasks or just use the following list:

• Find sutible python module which supports MQTT v5
• Create manual test implementation to check implementation details
• Extend the python template to support the generation
• Make sure the mqtt feature is strictly separate from the other features (customer should be able to choose either olink or mqtt without needing boths dependencies) - should it also be applied to requirements (dependencies)?
• Write documentation for this feature ( a simple document similar to Qt/C++ is sufficient until the full documentation is available)
• Write unit tests (optional, since networking tests are bit complex for unit tests)
