We will make use of common functions across the deploy_site, update_site and redeploy_server script. This will help to reduce common and repetitive codes across the scripts. Note that the Shipyard CLI needs to be installed before we can use these scripts. Change-Id: I31e5c8723346666a592951f59856008ccb64128bchanges/87/569187/1
