May I request a feature about Session status.

[CorvusYe]

Maybe we need a status in Session.
For example:

• NEW
• RUNNABLE
• RUNNING
• BROKEN

When the execution is completed and not released, it should be RUNNABLE status.

This feature can help developers use session multiple times and skip authentication. And different front end user can use different DB session in the same time not limited by synchronized.

The session status is transparent for users, and users need not to concern the session status. When a session is not released, you can use it continue without auth. And when you get a session from NebulaPool, it must be a new session, you can use it to execute statement too.
