- Add `--force` argument to `cmdeploy init` command
- Add startup for `fcgiwrap.service`
- Add extended check when installing `unbound.service`
- Add configuration parameters (`is_development_instance`, `use_foreign_cert_manager`, `acme_email`, `change_kernel_settings`, `fs_inotify_max_user_instances_and_watchers`)
