> {{uniqueKeys}} is a kind of constraint, it's unreasonable that {{uniqueKeys}} is a kind of statistic. so we should remove uniqueKeys from {{FlinkStatistic}} in blink planner. Some temporary solutions (e.g. {{RichTableSourceQueryOperation}}) should also be resolved after primaryKey is introduced in {{TableSchema}}
