add step to enforce requirement for maven version 3 or later
------------------------------------------------------------
Key: UIMA-2086
URL: https://issues.apache.org/jira/browse/UIMA-2086
Project: UIMA
Issue Type: Improvement
Components: Build, Packaging and Test
Reporter: Marshall Schor
Priority: Minor
A user had a build issue caused by using maven 2. Our poms have a prereq for
Maven 3, but this is apparently not "checked" by Maven. Add the check (try
using the enforcer plugin).
