apigee-go-gen creating custom template with updating apiproxy.yaml under oas3

[raghunathapalle]

Hi @lalevee, @ssvaidyanathan 

We are trying to create a custom template to include  multiple route rules using system.region.name variables (conditions) & also include corresponding targetservers in apiprpoxy.yaml under oas3 in apigee-go-gen but not successful. Does apigee-go-gen follow the apigeex apiproxy.xml indent or what tool could help create the yaml with correct indent?

RouteRule:
.name: east
Conditions:
- Condition: "system.region.name == 'east'"
TargetEndpoint: west
- RouteRule:
.name: west
Conditions:
- Condition: "system.region.name == 'west'"
TargetEndpoint: west
- RouteRule:
.name: default
TargetEndpoint: east
Conditions: []
TargetEndpoints:
- TargetEndpoint:
.name: west
