[ovirt-devel] use mvn instead of make to deploy

[Roy Golan]

just merged http://gerrit.ovirt.org/#/c/25661/ to help us use mvn to 
copy the project artifact instead of make.

usage:

#build and deploy to $OVIRT_ENGINE_PREIFX
mvn clean install -Pmake

#just deploy
mvn install -pl org.ovirt.engine:make -Pmake


#alternative prefix
mvn clean install -Pmake -Dprefix=/path/to/prefix
