title: Apache Airflow - Operator for creating a Compute Engine?
body: <p>I would like to use Apache Airflow to start n Compute Engine VMs to execute a specific code on each, I started looking at the <code>ComputeEngineStartInstanceOperator</code> but it seems it only can start an existing VM, not create a new one.</p>
  <p>Should I use the <code>BashOperator</code> or <code>PythonOperator</code> instead with something like: <code>gcloud compute instances create ...</code> or using Compute Engine python library ? or maybe Airflow is not the right tool for that kind of use ?</p>
  <p>If I use the <code>BashOperator</code>, how can I manage the connection to GCP safely ? With <code>ComputeEngineStartInstanceOperator</code> it's pretty easy to connect.</p>
