When shutting down FlowController, wait up to gracefulShutdownSeconds seconds for the components to stop before shutting down thread pools. This allows for asynchronous operations such as disableControllerServicesAsync to complete during shutdown. Updated StandardStatelessFlow so that on shutdown it catches more general Exception to ensure that shutdown succeeds
Ensure that Max Concurrent Tasks cannot be set less than 1 for stateless group; fixed typo in ProcessGroupDTO's docs; on shutdown, we may need to disable controller services asynchronously. At that point, the thread pool used to do so may already be shutdown. If so, catch this and create a new single-thread pool, disable the service, and immediately shutdown the pool. Also, if we fail to disable services on shutdown of a stateless flow, instead of throwing an Exception, just log it and move on - it doesn't make much sense for shutdown() to throw an Exception in that case.
Updated system tests so that when emptying a queue, we check the result and if the queue still has data (because a Processor hasn't acknowledged the data, for example) then continue issuing request until the queue fully becomes empty.
When shutting down input/output ports for stateless group, ensure that we wait for the ports' active threads to complete before returning
When stopping StatelessGroupNode, ensure that all the Processors, Controller Services (even those not executed by the Stateless Engine) are stopped/disabled before considering the Stateless Group to be fully STOPPED.

- Changed framework so that it serializes the dataflow into a VersionedDataflow using JSON as well as XML, and prefers the JSON representation on load, if it's available. This also results in the need for the cluster protocol to exchange its representation of the dataflow to using JSON. Rather than re-implementing all of the complex logic of Flow Fingerprinting, updated to just inherit the cluster's flow.
- Moved logic to synchronize Process Group with Versioned Process Group into a new ProcessGroupSynchronizer class instead of having all of the logic within StandardProcessGroup
- Reworked versioned components to use an instance id.
- Renamed StandardFlowSynchronizer to XmlFlowSynchronizer; introduced new StandardFlowSynchronizer that delegates to the appropriate (Xml or Versioned)FlowSynchronzer
- Updated to allow import of VersionedProcessGroup even if not all bundles are available - will now use ghost components
- Introduced a VersionedDataflow object to hold controller-level services, reporting tasks, parameter contexts, templates, etc.
- Allow mutable requests to be made while nodes are disconnected. Also fixed issue in AbstractPolicyBasedAuthorizer that caused ClassNotFoundException / NoClassDefFoundError if the authorizations were changed and then a node attempts to rejoin the cluster. The Authorizer was attempting to use XmlUtils, which is in nifi-security-utils and so so by madking nifi-security-utils a provided dependency of nifi-framework-api, but this doesn't work, because nifi-framework-api is loaded by a higher-level classloader, so the classloader that loads AbstractPolicyBasedAuthorizer will never have the appropriate classloader to provide nifi-security-utils. Addressed this by copying the code for creating a safe document builder from XmlUtils to AbstractPolicyBasedAuthorizer.
- Fixed bug that occurred when importing a Process Group that has 2 parameter contexts, one inheriting from another, where neither is pre-defined in the existing flow
- Fixed bug that was encountered when Updating a Versioned Process Group where one version had a disabled processor and the other had the processor running.
- Increased system-tests workflow timeout to 120 minutes
- Added additional exception handling to system tests

- Added totalActiveQueuedDuration and maxActiveQueuedDuration to the ConnectionStatus object
- Updated FlowFileQueue implementations and supporting code to properly calculate and provide the totalActiveQueuedDuration and maxActiveQueuedDuration for their active queues
- Fixing failing unit test. In examining this it appears that the unit test only accidentally passed in the past and that the object mocked to always throw an exception was not actually being used in the test.
- Adding UI component via ConnectionStatusDescriptor along with updates based on PR comments.
