"swagger generate cli" generates code that does not compile

[perelman92]

Problem statement

Running swagger generate cli generates code which cannot be compiled.

cli/runner_group_model.go:52:48: cannot use m (type *models.RunnerGroup) as type *models.Runner in argument to retrieveRunnerGroupNameFlags

cli/runner_model.go:27:6: registerRunnerGroupName redeclared in this block
       cli/runner_group_model.go:27:79: previous declaration

cli/runner_model.go:52:53: cannot use m (type *models.Runner) as type *models.RunnerGroup in argument to retrieveRunnerGroupNameFlags

Steps to reproduce

Use the swagger above.

$ swagger generate cli -f swagger.yaml
$ go build cmd/cli/main.go

Environment

swagger version: v0.28.0
go version: go1.17.1
OS: darwin/amd64

There is a name collision:
Runner - group_name ->RunnerGroupName
RunnerGroup - name -> RunnerGroupName

So generated code has duplicated functions.

Maybe the flag parsing and value reading should be refactored. Or deduplication name should be implemented.
PR welcome.

You can also override the generated name with x-go-name
