    ZEPPELIN-3246. Need option for automatically restart the livy interpreter 
automatically as zeppelin does not start new Livy session if yarn livy session 
application is killed

    ### What is this PR for?
    Add one new property `zeppelin.livy.restart_dead_session` to allow livy 
session to be created automatically. By default it is false, because there's 
many reason that session is dead, it is encouraged to ask user to check why it 
is dead and restart interpreter by themselves.
