    ZEPPELIN-3181. Enable impersonation support for kerberized cluster

    ### What is this PR for?
    This is to enable kerberos support for spark yarn mode in impersonation. 
Spark has one limitation that you can not specify keytab & proxyuser together. 
So this PR would run kinit before launching spark interpreter. so that user can 
enable impersonation for secured cluster.
