[Feature]: Support Azure Data Explorer as storage

[ThatRendle]

Requirement

As a developer at a site that prefers to use Azure Platform Services where available,
I want to use Azure Data Explorer (Kusto) as a storage backend for Jaeger
So that I can have a decent UX for exploring traces instead of the Azure Portal

Problem

Nobody on the platform engineering team has an appetite for maintaining a Cassandra or Elasticsearch cluster, so we are currently writing traces to Azure Monitor but I'm leading an effort to switch to Azure Data Explorer. There's a reasonable UX for logs, and metrics can be surfaced in Grafana, but there's basically nothing for traces. If Jaeger supported ADX as a persistence backend, I could persuade people that we could use the Jaeger UI.

Proposal

Reach out to the Azure Data Explorer team and get them to contribute a storage backend or plug-in? They seem pretty keen on creating integrations.

Open questions

Jaeger project does not support proprietary storage solutions as official backends for Jaeger, only open source databases. The best path for proprietary storage is to implement support for Jaeger's Remote Storage API (rather than a plugin route).
