Introduce a method in DependencyFacet to add a dependency to the <dependencyManagement> and <dependencies> sections at once

DependencyFacet.addDirectManagedDependency adds the dependency to the dependencyManagement section.
We should either:
a) Change this method to add to dependencyManagement AND dependency sections
b) Create a new method in DependencyFacet to do that

DependencyFacet should be have a method like this DependencyFacet.addDependency(POM_DEPENDENCY)
to add a Dependency based on a ManagedDependency
