NIFI-9794: If a node is OFFLOADING, do not allow connections to be deleted.
Also if we fail to notify the node that it needs to offload its data, change
its state back to DISCONNECTED. (#5865)
> We should not allow modifications to the flow while a node is in a state of
> OFFLOADING.

> In 1.16 we now allow the cluster flow to be modified while a node is
> disconnected, or in any other state except for CONNECTING. We should also not
> allow the cluster to be modified while a node is offloading. If we do allow
> the cluster's flow to be modified while a node is offloading, it's possible
> that a connection will be removed while the node is offloading data to that
> connection, and the node will never complete.
> At a minimum, we should disallow deleting a connection while a node is
> offloading.
