Deploy deployment test jars in local repository

Currently Deployment tests are using jars built by Unit tests run previously.

By convention, these jars are retrieved in the target directory by Deployment Tests.

Since we want to refactor and extract Deployment Tests (NXS-2470) in different module per target platform (to isolate jvm , java8, java7, etc..), we need to change this convention and instead of retrieving the test.jars in target directory we will deploy them in mvn repo with porper group, artifactId, version , classifier.
