Do not notify of change-lock if env is locked
Our deployer pipelines start with the change-lock job, notifying in #g_delivery if we are in a PCL period and aborting the pipeline. Those notifications can be annoying, because sometimes we don't want to pause auto_deploy during a soft PCL to be able to still deploy to canary once a day. In that case we simply lock the environment but leave auto_deploys enabled. But the check if the environment is locked is happining in the prepare job which is running after the change-lock job.
We should not notify that we are in a PCL period if the environment is locked anyway.
