generator ignore package passed for model and API for go generator

[waytoharish]

Hi Team,
I am trying to generate the Go-Srever code using the openapi-generator-cli.jar and passing model and API package name but code is getting generated in the same folder only.
Please suggest me if i am doing anything wrong.Command used-
java -jar openapi-generator-cli.jar generate -i http://petstore.swagger.io/v2/swagger.json -l go-server -o testgo --model-package=api.model

@waytoharish as mentionned in #2752 , the go generator doesn't actually support generating model and api in a specific folder
