Simplify importer rake tasks

- Remove Icinga_check method, which hasn't been doing anything since we moved to K8s
- Remove self.import method, which doesn't simplify calls enough to be worth the additional code.
- Update the calling rake tasks to use the new code, fix tests
- Remove brakeman ignore file related to icinga_check
