Create an Automatic Service Principal Azure RM Service Connection in Azure DevOps via Azure CLI

With more and more of our development and infrastructure projects being built and released via Azure DevOps, I find myself creating a few DevOps projects which, at creation time, share identical configs like service connections, permissions, repository names etc. Therefore, this week I have been trying to automate the creation of Azure DevOps projects. Many of the configs are easily configurable with AzureCLI and the Devops extension of it, but one thing I was struggling with was the creation of the service connections to our Azure subscriptions the way we do it from the GUI. We are using the Automatic Option when setting up the service connections for each one of our Azure subscriptions.
