[SPARK-16014][SQL] Rename optimizer rules to be more consistent
## What changes were proposed in this pull request?
This small patch renames a few optimizer rules to make the naming more
consistent, e.g. class name start with a verb. The main important "fix" is
probably SamplePushDown -> PushProjectThroughSample. SamplePushDown is actually
the wrong name, since the rule is not about pushing Sample down.
## How was this patch tested?
Updated test cases.
