[ZEPPELIN-2698] Apply KerberosInterpreter to JDBCInterpreter ### What is this PR for? This is to apply new KerberosInterpreter mechanism to JDBCInterpreter for relogin from keytab, instead of on fail relogin. ### What type of PR is it? [Refactoring] ### What is the Jira issue? * [ZEPPELIN-2698](https://issues.apache.org/jira/browse/ZEPPELIN-2698) ### How should this be tested? In JDBC interpreter setting add following properties - zeppelin.jdbc.auth.type = KERBEROS - zeppelin.jdbc.principal = principal value - zeppelin.jdbc.keytab.location = keytab location Now try and run any of hive's query (say `show tables`) it should return with valid results. Again, wait for this kerberos ticket to expire (usually its 24hrs) then try the above again, and it should work. ### Questions: * Does the licenses files need update? N/A * Is there breaking changes for older versions? N/A * Does this needs documentation?
