ZEPPELIN-2102: Restart interpreter automatically
### What is this PR for?
Sparkcontext is shutdown in following cases
1. calling `sc.stop` explicitly
In this case, the user has to manually restart the interpreter to submit
his next spark job
2. OOM error from spark
Restarting of interpreter will not help. The only recovery is restarting
zeppelin server
I have not enumerated all the cases in which sc can go down. There might be
other cases.
In this PR, restarting interpreter automatically
