NIFI-11591 Corrected intermittent system test failures
When waiting for a Processor to stop completely in system tests, also consider
any terminated threads. Consider the processor stopped only when all active
threads and all terminated threads have gone to 0. Additionally, when stopping
all components in a Process Group, wait for the PG to reflect that there are no
running components. Previously, we checked for processor active thread counts.
However, this was problematic because the flow that was fetched was not fetched
recursively and as a result, processors running in embedded groups were not
always stopped when the waitForProcessorsStopped(String groupId) method
returned. Finally, removed the step for gathering surefire-reports in failed
system tests because it was not working as expected and was unneeded because
the tests' logs were already gathered into the diagnostic dump that is uploaded.
Added fix for BatchFlowBetweenGroupsIT. The test would intermittently fail,
based on timing. The test assumed that when Input Port in Group B was scheduled
to run, it would trigger before FlowFiles in Group A finished processing. The
Sleep processor caused a 10 ms delay for each of 5 FlowFiles which gives the
Input Port about 50 ms to trigger. If it took longer to trigger the first time,
the test failed. Adjusted the Sleep processor to use 2 seconds. So now instead
of 50 milliseconds to start, it has 10 seconds. Overall this adds about 30-45
seconds to the run time of the test but ensures more-than-adequate time for the
test to run, even on extremely slow hardware
This closes #7289

> We've been seeing intermittent failures in the following system tests:
> - DynamicClasspathModificationIT
> - RegistryClientIT#testControllerServiceUpdateWhileRunning
> - ClusteredRegistryClientIT#testControllerServiceUpdateWhileRunning
> Additionally, NIFI-11557 introduced a surefire-report step in the system
> tests to attempt to capture more logs from failures, but that step is not
> working as expected and additionally it appears that the log output from the
> tests themselves is already captured into the diagnostic dump that is
> included.
