NIFI-443: If a funnel is given an incoming connection but has no outgoing
connection, it continually runs and fails, logging a lot of ERROR messages
> Funnels can become permanently stopped.

> Attachments:
> 0001-NIFI-443-Always-start-funnels-when-added-to-process-.patch,

> Funnels can become permanently stopped if they are loaded from a template or
> if NiFi is ever restarted with nifi.flowcontroller.autoResumeState= is set to
> false.
> The only way to get data flowing again is to replace the permanently stopped
> funnels with new funnels. There is no way to select a funnel and hit play
> (ineligible component).
> Templates that contain funnels are not usable without being manually fixed
> after addition to the graph.
> If a NiFi instance is ever restarted with auto resume state set to false,
> every funnel on the graph will need to be replaced.
