Create the deploy function.
This script can be put on $DEPLOYIT_CLI_HOME/ext

@bmoussaud: when I am running deploy command. I am getting below error.
javax.ws.rs.ProcessingException: com.thoughtworks.xstream.converters.ConversionException:

@vrathore18 this script uses an old API to interact with the tasks. the script should be updated to use task2. object.
