acs-engine deploy fails for Azure US Government due to template parameters for AzurePublicCloud

[gsacavdm]

---

Is this an ISSUE or FEATURE REQUEST?: Issue

What version of acs-engine?: v0.13.1

Orchestrator and version (e.g. Kubernetes, DC/OS, Swarm): Kubernetes

What happened: Running acs-engine deploy --api-model apimodel.json --location usgovvirginia --azure-env AzureUSGovernmentCloud results in a deployment that does not have the appropriate template parameters for AzureUSGovernment, rather it has the parameters for AzurePublic:

• OSImageVersion: 16.04.201801260
• fqdnEndpointSuffix: cloudapp.azure.com
• targetEnvironment: AzurePublicCloud

You can check these in the Azure portal, navigate to the resource group created by acs-engine deploy, click on Deployments, select the deployment and look at the parameters.

What you expected to happen: The resulting Azure deployment should have the appropriate AzureUSGovernment template parameters set:

• OSImageVersion: latest
• fqdnEndpointSuffix: cloudapp.usgovcloudapi.net
• targetEnvironment: AzureUSGovernmentCloud

How to reproduce it (as minimally and precisely as possible):
Run the command noted above.
