Unify code formatting, static analysers and linters for all microservices

[khyurri]

We're going to use:

• black as formatting tool with 79 symbols per line
• strict pylint
• strict mypy

During this task we need to add formatters and linters into GitHub actions and into pre-commit hooks for all microservices
