joining strings in confd templates

With confd sometimes you will want to join a bunch of keys together into a line with comma separated values.  Here is a template snippet to do that:

servers={{range $index,$server := .myapp_servers}}{{if $index}},"{{$server.Value}}"{{else}}"{{$server.Value}}"{{end}}{{end}}
