[Feature]: Add support to query for dependencies in api/v3 API

[jcolladokuri]

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.
