* refactor: Partially break core package into dns, result and ssh packages * refactor: Move core package to config/endpoint * refactor: Fix warning about overlapping imported package name with endpoint variable * refactor: Rename EndpointStatus to Status * refactor: Merge result pkg back into endpoint pkg, because it makes more sense * refactor: Rename parameter r to result in Condition.evaluate * refactor: Rename parameter r to result * refactor: Revert accidental change to endpoint.TypeDNS * refactor: Rename parameter r to result * refactor: Merge util package into endpoint package * refactor: Rename parameter r to result
