Cleanup the Dependency Object

Currently, we have had two contributors add a duplicative feature to the dependency object and the analysis. Specifically the following three fields:

```java
Dependency.packagePath
Dependency.name
Dependency.version
```

These are also duplicative of the `Identifiers` collection. This needs to be refactored to consolidate and make the usage common across analyzers.

As this could affect #1276 - these two enhancements should likely be done at the same time.
