Installation of regular node does not allow choose of "data" directory

[alejandroalffer]

In earlier versions of general node installation script the data volume can be choose, and these feature has been removed. The current ledger size is close to 40Gb, and its a good practique, specially in a Docker enviroment, or shared servers keep the data volume in out of node working directory

[...]
function setVolume {
  echo "Set the absolute path of the data directory (ENTER default: pwd): "
  read DATA_DIR
  echo ""
  WORK_DIR="$(pwd)"/alastria
  DATA_DIR=${DATA_DIR:-$WORK_DIR}
}
[...]

I'm fixing current init.sh file to make it work again, and extend this option to the Dockerfile

Resolved in alastria-node-t branch, as the new proporsal for direct way for installation of AlastriaT node.
