Support Jaeger query APIs

[zyy17]

What problem does the new feature solve?

The current GreptimeDB supports ingesting trace data by OTel; however, we don't provide a better way to render the data. To use Grafana or Jaeger UI, we should support Jaeger query APIs.

What does the feature do?

Implement Jaeger query APIs.

Implementation challenges

Although the Jaeger has v2 and v3 APIs, the v2 APIs are more compatible. We can implement v2 APIs at first.

The following APIs are used in Grafana Jaeger datasource:

• /api/services/;
• /api/traces;
• /api/dependencies: Actually, get dependencies can be a flow task in GreptimeDB;
