Add podman Quadlet modules

This commit introduces two new modules for managing Podman Quadlets:

- podman_quadlet: Install and remove Podman Quadlet files
  * Supports installing single files, directories, and additional config files
  * Implements idempotent state management (present/absent)
  * Validates parameters and provides meaningful error messages
  * Default force=true for removal operations
  * Removed deprecated 'ignore' parameter in favor of built-in idempotency

- podman_quadlet_info: Gather information about installed Quadlets
  * Lists all installed quadlets or prints specific quadlet content
  * Supports filtering by quadlet kinds (container, pod, network, etc.)
  * Provides detailed quadlet metadata including status and paths

Key features:
- Shared utilities in module_utils/podman/quadlet.py for code reuse
- Comprehensive integration tests for both modules
- Full idempotency support for all operations
- Proper handling of edge cases (missing files, malformed quadlets, etc.)
- Check mode support for safe dry-run operations
- Extensive documentation and examples

The modules use relative imports for module_utils to support local
development and testing with the containers.podman collection.
