'Deletes the draft configuration associated with the running
environment.  Updating a running environment with any
configuration changes creates a draft configuration set. You can
get the draft configuration using DescribeConfigurationSettings
while the update is in progress or if the update fails. The
DeploymentStatus for the draft configuration indicates whether
the deployment is in process or has failed. The draft
configuration remains in existence until it is deleted with this
action.
