> Make Executor stateful in sql client

> Currently sql client is stateless, it read config files into `Environment`
> and recorded all session changes into `SessionContext`.
> Each time sql client want to execute a new command, we have to first
> construct `ExecutionContext` by combining `Environment` and `SessionContext`,
> and then transfer all information into a new `EnvironmentInstance`.
> It works well before but kind of hard to extend now. One example is support
> creating table in sql client. We have to remember create statements and
> replay them every time we want to execute a new command.
> If we can make sql client stateful, and table environment be the state of sql
> client, things will be much more easier.
> This Jira should revisit all related classes, and define a clean relationship
> between old roles after making sql client stateful.
