Create the config manager module and initialize project

[Enaraque]

Description

The purpose of this PR is to add the first module of the new Installation Assistant: the Config Manager. Alongside this module, the pyproject.toml is included to initialize the project, as well as the logger that will be used.

The pyproject.toml defines the project dependencies and the different Hatch environments that can be used during development. The idea is that, once completed, the project can be easily built with Hatch using the configuration defined in the pyproject.

The Config Manager is responsible for retrieving information about each component and node defined in the config.yaml.

Tests 🧪

You can find different executions of the Config Manager in a comment in the related issue: #336 (comment)

A test module has also been created, which will be extended as new features are added to the project. For now, unit tests have been added for both the Config Manager and the logger.

You can run the tests with:

hatch run dev:test-cov

This will install the required dependencies and print a summary of the test execution along with the test coverage percentage. In this case, the obtained coverage is 100%:
