> Flow restart could double-spend flowfiles

> Project: Apache NiFi MiNiFi C++

> Time Spent: 2h 50m

> Flowfiles are async-deleted from the FlowFileRepository and no flush happens
> after shutdown, leaving these marked files in the repository. If we restart
> the agent, this allows these zombie files to be resurrected and be put back
> into their last connections. This could cause files to be processed multiple
> times even if we marked them for deletion.
> Solution proposal: flush the FlowFileRepository after shutdown, so all marked
> files are actually deleted (this won't save us from double-processing
> flowfiles after a crash)
> (also make sure that the FlowFileRepository shutdown happens after no more
> processors are running)
