    [FLINK-6089] [table] Implement decoration phase for rewriting predicated logical plan
after volcano optimization phase

    At present, there is no chance to modify the DataStreamRel tree after the volcano optimization.
This pr consider to add a decoration phase after volcano optimization phase. Decoration phase
is dedicated for rewriting predicated logical plan and is independent of cost module. After
decoration phase is added, we get the chance to apply retraction rules at this phase (The
next jira[FLINK-6090] will add retraction rules at decorate phase).
