Updates needed for shared Maven instructions

This is from psakar@redhat.com on HipChat:

@SandeGilda @ctomc @NikoletaZiakova Who is responsible for page https://github.com/jboss-developer/jboss-developer-shared-resources/blob/master/guides/CONFIGURE_MAVEN_JBOSS_EAP7.md#configure-maven-to-build-and-deploy-the-quickstarts ?
It contains obsolete or wrong instructions with respect to required maven version - "You plan to use Maven command line and have already installed Maven 3.1.1 or later. In this case, you should already be configured to build and deploy the quickstarts. If you installed Maven 3.2.2, you must update to Maven 3.2.3 or later."
Quickstarts for EAP 7.1 are enforcing maven 3.2.0 or later - "[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message:
To build this project Maven 3.2.0 (or greater) is required. Please install it."

I also noted it refers to older unsupported version of JBDS in the instructions.
