core: integrate make into maven

Use maven to deploy the artifact to prefix using make:

  #exclusivly deploy from ovirt-engine root

  mvn install -pl org.ovirt.engine:make -Pmake

  #build the project and deploy to $OVIRT_ENGINE_PREFIX

  mvn clean install -Pmake

  #For explicit prefix use:

  mvn install -Pmake -Dprefix=/path/to/prefix

The prefix defaults to env variable OVIRT_ENGINE_PREFIX
