Update schema, features.json and add feature list xml to 23.0.0.9

[cherylking]

Now that 23.0.0.9 is available, update the cached features.json and server.xsd to that level. Also generate a featurelist.xml and store it to be used for config element validation (need separate PR to actually use it). Be sure to post process the server.xsd to remove the any attribute for anything without extra properties, and use both options --schemaVersion=1.1 and --outputVersion=2?
