Review Comment:
   I think we don't need to do this under the `manageWorkers()` because there 
is no conditional variable waiting to be notified, so this issue won't happen 
there, the worst that could happen that the loop will run one more time after 
the thread pool is stopped, but the shutdown will wait for it to join.
   
   The `running_` variable seems to be still used in other occurrences without 
a mutex, and as there are 2 mutexes here under which we also use the `running_` 
variable it could still happen that it is used by multiple threads so I would 
keep it as an atomic.
   
   It's a good pont that `adjust_threads_` is unused, I removed it in 
https://github.com/apache/nifi-minifi-cpp/pull/2019/commits/6931a54bf6e7e118f95fb162a4a569590ebcabc7
