Note that in the event where the 'deploy_site' Action is triggered
from Shipyard, the 'parent_dag_name' variable gets assigned with
'deploy_site.validate_site_design'. The name of the main dag will
be the front part of that value, i.e. 'deploy_site'. Hence we will
extract the front part and assign it to main_dag for the functions
defined below
