title: How to sync Argo workflow-templates b/w a git-repo and Argo instance?
body: <p>I have a git repository(hosted on Github) where I create my workflow-template YAMLs, and upload them to Argo via UI or REST-api. Now whenever I update any workflow-template, I have to manually update it in 2 places, the git-repo and Argo. There is a chance of either place being missed in this process.<br />
  How can I automate the process of updating workflow-templates in Argo-service, whenever the workflow-templates in git repository change?</p>
