Title: Allowing for --update-snapshots to be optionally defined

During development of a multiple pom project, sometimes its useful to tell maven to update the snapshots instead of having to clear the M2 repository cache and having it have to redownload all of the other dependencies. This change allows the developer to do set an environmental variable for the app to tell it to have maven update the snapshot dependencies of a project.
