Subject: [PATCH] Sort hosts before writing them to a file

The hosts might be generated in a non-deterministic order (e.g. from
PuppetDB). If that's the case, then the configuration file they're
written to will change every run.

This ensures that they are always written consistently and avoids
spurious change reports.
