[SPARK-13424][SQL] Improve test coverage of EnsureRequirements [WIP]
### What changes were proposed in this pull request?
Improve the testing of the `EnsureRequirements` planner rule. This is a
Work-in-Progress. The PR currently only consolidates a number of existing

matrix to test every possible combination of the following dimensions:
- Distributions & Partitions
- UnspecifiedDistribution
- AllTuples
- ClusteredDistribution
- Partial clustered distribution
- OrderedDistribution
- BroadcastDistribution
- The number of partitions.
- Sorting
- Partial ordering
