[HOTFIX][ZEPPELIN-2294]. Interpreter fail exception is not propagated to frontend

### What is this PR for?

This PR would address the issue of Interpreter fail exception is not propagated to frontend. This is due to the bug fix of restarting button issue.  Make referenceCount as number of sessions attached to this process. Open and close all the interpreters in one session together. I don't think there's scenario for close a single interpreter for now.
