make the paramter noscripting of mongodb configurable

I have make the parameter "noscripting" configurable on mongodb by make the following changes. 
After doing this, you can add one line in your deployment yaml file like following to make "noscripting" parameter configurable:
mongodb_node:
    supported_versions: ["2.2"]
    default_version: "2.2"
    max_tmp: 900
+   noscripting: false
