Improve deploy script

- Wait for NC instance to be ready to call Let's Encrypt script.
- Add parameter to build or not container images.

deploy.sh

 #!/bin/bash
 
 STACK_NAME=$1
-
+BUILD=$2
+if [ -z $BUILD ]; then
+    BUILD=1;
+fi
 if [ $# -eq 0 ]; then
     echo "You must pass stack name as a parameter"
     exit 1
 docker stack rm ${STACK_NAME}
 
 # Build images

-docker push bingen/rpi-haproxy
-docker push bingen/rpi-mailserver
