Environments variables toml configuration

Description:
Hi folks

I'm trying to configure those parameters in deployment.toml:

[[apim.gateway.environment]]
ws_endpoint = "ws://$env{HOST}:9099"
wss_endpoint = "wss://$env{HOST}:8099"
http_endpoint = "http://$env{HOST}:${http.nio.port}"
https_endpoint = "https://$env{HOST}:${https.nio.port}"

[apim.devportal]
url = "https://$env{DNS}:${mgt.transport.https.port}/devportal"

And when I checked at api-manager.xml it is:

<Environment type="hybrid" api-console="true" isDefault="true">
  <!-- Endpoint URLs for the APIs hosted in this API gateway.-->
  <GatewayEndpoint>https://$env{DNS}:${https.nio.port},http://$env{DNS}:${http.nio.port}</GatewayEndpoint>
  <!-- Endpoint URLs of the WebSocket APIs hosted in this API Gateway -->
  <GatewayWSEndpoint>ws://$env{DNS}:9099,wss://$env{DNS}:8099</GatewayWSEndpoint>
</Environment>

I wonder if there is a workaround to solve this issue.
