Do not block value processing to request metadata lookups
- Try again with the logging without interval.tick
- Add a timeout around queries to the bus
- Re-enable the zbus tokio integration
- Make a specific connection to dbus for metadata
- WIP: This is just metadata loop spun out. left to do is to move metadata signal polling into the metadata part, and figure out how to give signal loop a handle to it to query metadata. Perhaps a simple arc or shared ref will be enoug?
- Separate metadata processing from the value processing
- Place placeholder items on values we query before we continue
