描述

Requirement

In Grafana to be able to visualize the dependency graph we are using api/dependencies. We are trying to migrate to api/v3 but it does not seem like this supports querying for dependencies.

Problem

We are unable to migrate away from the internal API for dependency graph without the support of dependencies in the api/v3/* endpoint

Proposal

Add support to query for dependencies in the api/v3/ endpoint.

研究方向
First, review the existing internal API endpoint `api/dependencies` in `cmd/query/app/` and its implementation. Then, examine the `api/v3` swagger specification at `https://github.com/jaegertracing/jaeger idl/blob/main/swagger/api v3/query service.swagger.json` to understand the expected endpoint structure. Look at how other endpoints in `api/v3` are implemented, such as `api/v3/services`. Check any discussions or linked PRs in this issue for guidance on implementation.
