ITDependencies (Zipkin Interop Tests 2.19.0 API)

java.lang.Object
- zipkin2.storage.ITStorage<T>
- - zipkin2.storage.ITDependencies<T>

```
@TestInstance(PER_CLASS)
public abstract class ITDependencies<T extends StorageComponent>
extends ITStorage<T>
```
Base test for SpanStore implementations that support dependency aggregation. Subtypes should create a connection to a real backend, even if that backend is in-process.
This is a replacement for zipkin.storage.DependenciesTest. There is some redundancy as zipkin2.internal.DependencyLinkerTest also defines many of these tests. The redundancy helps ensure integrated storage doesn't fail due to mismapping of data, for example.
