Pull Request Overview

This PR implements hostname-based naming conventions for LXD host registration with MAAS instead of using IP addresses, along with significant code refactoring to improve maintainability and structure.

• Use hostname-based naming convention (lxd-host-<hostname>) for LXD host registration instead of IP-based naming
• Refactor machine deletion logic into smaller, more focused functions
• Update LXD initializer to use normalized node names and clean up commented code

The check for empty hostname suffix is fragile. If m.Hostname is empty or whitespace-only, canonicalLXDHostName will return 'lxd-host-' which matches this condition, but this logic assumes the hostname is always non-empty after trimming. Consider checking strings.TrimSpace(m.Hostname) == \"\" directly before calling canonicalLXDHostName.

Same issue as above - the check for empty hostname suffix is duplicated and fragile. Consider extracting this validation into a helper function or checking the hostname before calling canonicalLXDHostName.
