NIFI-3472 NIFI-4350 Removed explicit relogin code from HDFS/Hive/HBase components and updated SecurityUtils.loginKerberos to use UGI.loginUserFromKeytab. This brings those components in line with daemon-process-style usage, made possible by NiFi's InstanceClassloader isolation. Relogin (on ticket expiry/connection failure) can now be properly handled by hadoop-client code implicitly.
NIFI-3472 Added default value (true) for javax.security.auth.useSubjectCredsOnly to bootstrap.conf
NIFI-3472 Added javadoc explaining the removal of explicit relogin threads and usage of UGI.loginUserFromKeytab
Readded Relogin Period property to AbstractHadoopProcessor, and updated its documentation to indicate that it is now a deprecated property
Additional cleanup of code that referenced relogin periods
Marked KerberosTicketRenewer is deprecated
NIFI-3472 Cleaned up imports in TestPutHiveStreaming
