Major update: XML configuration out, YAML in. Plus tons of other things.

[Vadim Tkachenko]

Hello lurkers,

The reactive tree now reads the configuration from a YAML file. That's the change visible on the surface, but to make it happen a serious system reengineering was necessary, and that gave me a chance to revisit and improve the architecture - I'm now much happier with it than I was before gh47 work started. To save you a few clicks, here's a summary of changes (available dynamically updated here):

• Drastically simplified configuration (YAML instead of XML)
• The configuration is documented and code assist is supported by modern IDEs (thanks to Spring Configuration Metadata)
• Can now be run in a Docker container
• Better device support (ESPHome, Zigbee, Z-Wave)
• Zones now support min/max allowed range, per zone
  
• Special note: economizer support, $$$ saved
• Drastically improved startup time
  
• More ways to run (standalone, SpringBoot, Quarkus, Docker)
• Improved platform instrumentation (Micrometer to InfluxDb)
• Improved system instrumentation ("instrument cluster", documentation coming)

Disadvantages:

• Some subsystems (1-Wire, XBee, shell) have not yet been ported over from the last reactive snapshot - coming up
• Needs Java 17
• Has not yet been verified to run on Raspberry Pi 3B
• Bleeding edge - but it's being dogfooded, so it'll stop bleeding fast

If you ever tried to get DZ running - you know how much of a PITA the XML configuration was. And just take at how simple it is now. And, code assist - can't beat that.

Enjoy.

PS: The old reactive tree with XML configuration is still available as a tag: https://github.com/home-climate-control/dz/releases/tag/reactive-last-xml. I have a hunch it will not be much sought after, though.
