Initial port of KNELServerBuild to FetchApply framework

- Created base FetchApply directory structure with classes, initializers, modules, roles, and variables
- Ported SetupNewSystem.sh functionality to modular FetchApply structure
- Created server classes: physical, virtual, librenms, database, webserver, dev-workstation
- Implemented initializers for system-setup, packages, ssh-keys, and user-configuration
- Created modules for oam, system-config, ssh-hardening, and librenms-agent
- Defined security and monitoring roles
- Copied configuration templates from KNELServerBuild
- Updated README with comprehensive FetchApply usage instructions
