Create generified primitive serializers, and test them, for all avro primitive types.
Static schema registries need synchronization (yay for parallel test execution!)
Get rid of old multiple primitive avro serializers in favor of combined one.
Basic working on-demand julia demo.  Stuff works, but not well.  The biggest issues still extant are that the spark job web page doesn't work (so we can't see how things are going), and request caching and combining doesn't seem to be working.
Fix case problem when reading client tile request parameters.
Get rid of specialized string array serializer, the primitive array serializer handles it.
We may want this back at some point to avoid overuse of the more-opaque-than-string Utf8, but we can decide that as an independent matter, when all is clean.
Partial, unworking checkin so I can switch computers
Working generic array of pair serializers
Get rid of demo-specific avro schema from the general project.
More tests of the new generic serializers and their construction.

On demand regressions
refs #8491 - updating node renderers to new render themes.
Added example to QueryParamDecoder doc. Added proper logging of errors in new ConfigurableFactory methods. Removed unused method from TileResource.
