allow running inspection hooks on redfish interface

Added the redfish inspection interface to be able to run inspection
hooks in the conductor on the inspection data in the same way the agent
inspection interface operates. Removed the special casing of the
processor and the PXE interface since we now use the standard hooks to
populate this data. Fixed up some tests on node properties to now show
that the data matches correctly.

+    Adds inspection hooks in the redfish inspect interface for processing data
+    received during inspection. The three default configuration hooks
+    `validate-interfaces`, `ports` and `architecture` are added. A new
+    configuration option `inspection_hooks` is added in the `redfish`
+    configuration section.
