muti-node database options

[errordeveloper]

Trace ID are currently stored locally in an ephemeral store using Badger. It would be easy to enable persistence across restarts, but in oder to run hubble-otel on each node, there will need to be an alternative database option. It's also possible Badger might work on top of a volume, which maybe worse investigating. It'd be quite viable to use a hosted K/V store instead.
