The commit refactors the distributed optimizer to work according to thanos-io#483: 1. Classify each subtree as non-distributive, distributable as-is, or distributable through an aggregation, avg, or absent rewrite. A parent can absorb only children that are distributable as-is. 2. Select the roots of maximal distributable subtrees. These are nodes with a distribution strategy whose parent has none. 3. Replace each selected subtree with the remote plan for its strategy.
