> Currentlly, some code are duplicated in `StreamExecJoinRule`、`StreamExecIntervalJoinRule` and `StreamExecTemporalJoinRule`, this JIRA tries to eliminate the code duplication, so we can maintain code easier.
> `StreamExecJoinRule`、`StreamExecIntervalJoinRule` and `StreamExecTemporalJoinRule` 
> are rules for stream-stream join with different match condition, we can add an abstract class `StreamExecJoinRuleBase` as a base implementation for them.
