Run NuBot using a script that intercept nubot shutdowns (and act)

Since the java is not able to intercept a kill -9 event, NuBot should be wrapped around a script that detects it (see [1]) and clear active orders and liquidityinfo .

The solution below is only valid for unix system, while we want to make it system independent :

#!/bin/bash

#Concatenate arguments 
args=""
for var in "$@"
do
    args+=$var
done
    echo "$args"
java -jar NuBot $args

wait
# It gets here when the app quits, even with forced kill -9 <pid>
echo "NuBot was shut down. Executing the termination script to make sure all orders are cleaned up and liquidity info reset"
# Execute the cleanup using the same arguments
#java -jar NuBot kill $args
