Summary

Current version, doctrine/orm will generate a relationship table contains only two column(just like user_id, role_id).
It is hard for developer to extends this table, like add create time column, create user id and so on.
Add new \Doctrine\ORM\Tools\ToolEvents::postGatherRelationsSql and trigger in \Doctrine\ORM\Tools\SchemaTool::gatherRelationsSql, then developer can write custom logic for they owned.
