Description
Provide a generic mechanism for plugins to inject rules into the AQE "query prep" stage that happens before query stage creation.
this goes along with https://issues.apache.org/jira/browse/SPARK-32332 where the current AQE implementation doesn't allow for users to properly extend it for columnar processing.
The issue here is that we create new query stages but we do not have access to the parent plan of the new query stage so certain things can not be determined because you have to know what the parent did. With this change it would allow you to add TAGs to be able to figure out what is going on.
