* Make interfaces more specific than "MDS" - Introduce `dax.Schemar` interface - Introduce `dax.Noder` interface - The rest is generally to standardize on the new interfaces. - Remove `pilosa.SchemaInfoAPI` interface - Move `TranslateNode` and `ComputeNode` types from controller to dax package - Remove `queryer.FeatureBaseImporter` - Remove `queryer.MDS` interface - Remove `queryer.Importer` interface - Identify types using an "MDS" interface and split into Noder/Schemar as necessary - Changed `Queryer.orchestrator` to a `map[qual]*qualifiedOrchestrator` because we can't share an orchestrator across quals * Convert orchestrator to use TableKeyer
