Summary: Add support for query timeout in Hive processors

With HIVE-4924 it is possible to set a query timeout when executing a query
against Hive (starting with Hive 2.1). Right now, NiFi is built using Hive
1.2.1 and this feature is not available by default (the method is not
implemented in the driver). However, if building NiFi with specific profiles
this feature can be used.
The objective is to expose the query timeout parameter in the processor and
enable expression language. If the version of the driver is not implementing
the query timeout the processor will be in invalid state (unless expression
language is used, and in this case, the flow file will be routed to the failure
relationship).
