[MSHARED-632] Expose which dependency classes are used and where
We use the maven-dependency-plugin to analyze dependencies and fail our
build if there are any used undeclared or unused declared dependencies. In the
case of used undeclared dependencies, it is often helpful to know which classes
are being used and where they are being used. We've found a few workarounds to
make this a little easier, but the plugin has access to this information so
what we really want is for the plugin to just print this info along with each
used undeclared dependency. We've made this change in our fork and our
developers are very happy with it, so I'd like to contribute it back
([here](https://gist.github.com/jhaber/d8204829fe61569e0034250df74300fb) is an
example of the output before and after the change).
If you agree this is a useful feature, this PR implements the first step
which is to update the maven-dependency-analyzer to return this information so
that the maven-dependency-plugin can use it.
I introduced a new interface, `DependencyAnalyzerWithUsages`, to avoid
breaking changes to the `DependencyAnalyzer` interface. I confirmed with the
japi-compliance-checker that source and binary compatibility has been
maintained:
```

-jdk-path $JAVA7_HOME -old ~/Downloads/maven-dependency-analyzer-1.6.jar -new
~/src/maven-shared-pr/maven-dependency-analyzer/target/maven-dependency-analyzer-1.7-SNAPSHOT.jar
