Add Core Commands

1. Create a new command class in the appropriate namespace under src/N98/Magento/Command/
2. Extend the AbstractMagentoCommand class
3. Implement the configure() and execute() methods
4. Add appropriate tests (Unit-Test and bats) for your command
5. In the docs/docs/command-reference/ directory, add an entry for your command category (e.g., cache/index.md) that lists the command names and links to their dedicated documentation files. Each command should have its own detailed documentation file (see below, for example).
