NIFI-1052: Added "Ghost" Processors, Reporting Tasks, Controller Services
If we try to create a component for which the NAR is missing, we previously
would throw an Exception that would result in NiFi not starting up. We changed
this so that we instead create a "Ghost" implementation that will be invalid an
explain that the component could not be created. This allows NiFi at least to
start, so that users can continue to use the NiFi instance.
This ticket also includes fixes to the ReportingTaskResource, as those were
necessary to test this.
Note that if a component is missing, all properties are marked as
'sensitive' simply because we don't know whether or not the property truly is
sensitive, and it is better to show the value as sensitive than to assume that
it is not. Unfortunately, this means that the actual property value can't be
seen unless the correct component is restored to the lib/ directory.
