MNG-5557: Constrain the set of projects that are passed into the ReactorReader as specified by --projects 

- Add some documentation about the lifecycle within DefaultMaven
- Remove the use of DelegatingLocalArtifactRepository in DefaultMaven as it has been replaced with the use of the
  ReactorReader which is an implementation of Aether's WorkspaceReader
- Localize the manipulation of the ProjectBuildingRequest to getProjectsFromReactor()
- Deprecated getLogger()
