 Review comment:
   I forget user could call ExecutionEnvironment multiple times. Generally 
speaking these envs have same configuration but if we then modify them in user 
code they should changed.
   
   The motivation I do this change is from `OptimizerPlanEnvironment` where 
return identical instance of env for all `getEnvironment` calls. However, 
`StreamPlanEnvironment` is different instance.
   
   As the semantic of `getEnvironment`, I think return different instance for 
each call is reasonable.
   
   Will update.
