Don't create duplicate deployments
What does this MR do?
When the API parameters for a deployment are the same as the last deployment no new deployment will be created. This prevents duplicate deployments if nothing changed. As such no hooks will be executed either, which prevents for example Slack notifications which don't add value.
Does this MR meet the acceptance criteria?
