NIFI-1697 Ensuring FlowController appropriately wraps code with NarClosable
From debugging this issue it was noticed that the problem only occurred
while a PutHDFS processor was enabled (running/stopepd), but if it was disabled
the problem went away. This led to realizing that when the processor is running
or stopped, validation is being called and was not being wrapped with
NarCloseable to ensure the validation uses the same classpath as the component
uses when executing.
This PR ensures that the FlowController wraps validation with NarCloseable,
and also when calling OnPrimaryNodeStateChanged which needed to be wrapped as
well.
