(feat): Format, label and mount and resize devices through configuration

[lasith-kg]

Description:
This pull request includes all the functionality to format, label and mount and resize devices through YAML configuration.
In addition, there is a comprehensive suite of test coverage that spans across all critical logic within the application and covers common scenarios that a user can realistically find themselves in. I estimate code coverage to be around >90%
