Config drive spec uses network_data.json

The filename was incorrectly implemented as network_info.json instead
of network_data.json. Support for reading the correct file already
exists in glean. As such, we need to write both files for user
compatability in the short term, and remove the second file at a
later point in time.

A release note has been added detailing this as well.

+deprecations:
+  - The ``node_network_info`` parameter has been deperecated
+    in favor for the ``node_network_data`` parameter as the
+    relaated configurtion drive ``network_info.json`` file was
+    misnamed origionally, and should have been named
+    ``network_data.json``.
+    Support for the node_network_info, and the continued
+    write-out of the network_info.json file in configuration
+    drives will be removed in the Queens cycle.
+fixes:
+  - When support for passing configuration drive data to the
+    nodes was originally created, the file was accidently named
+    incorrectly as ``network_info.json``.  The correct filename
+    is ``network_data.json``. Both files will now be written
+    until support for writing ``network_info.json`` is removed
+    in the Queens cycle.
