followup of #395. requiredVars now always come before optionalVars so there is no need to manually order the properties in openapi.yaml. This also solves the issue mentioned in #509.
I removed supportPython2 because we don't need to support py2.
I removed two default values in openapi.yaml. I don't think those default values do anything. Those two properties are required so they should not have a default value (the user needs to explicitly provide a value).
