interface Admin {
boolean datasetExists(String name);
@Nullable String getDatasetType(String name);
@Nullable DatasetProperties getDatasetProperties(String name);
void createDataset(String name, String type, DatasetProperties properties) throws DatasetManagementException;
void updateDataset(String name, DatasetProperties properties) throws DatasetManagementException;

void truncateDataset(String name) throws DatasetManagementException;

Why are we adding this to RuntimeContext, and not to DatasetContext? The idea is that DatasetContext represents a way to obtain an instance of a dataset in a transactional context. Admin operations are not transactional, and therefore it seems cleaner to add them separately from DatasetContext.
