> The initial temporal table join (FOR SYSTEM_TIME AS OF) is a Correlate, we need rewrite it into a Join to make join condition can be pushed-down. The join will be translated into  [[StreamExecLookupJoin]]  or  [[StreamExecTemporalJoin]] in physical. 
> Import  Temporal table join rule to deal above temporal join rewrite logic.
