Provide option to provide a variables list in the form schema response: so you don't need to query for variables

Would also support more struck variable API lock down so the schema can just return a single set of variables used by the form and nothing else.

[StephenOTT]

Override the service so the get form schema API will return a object with the schema and the variables

[StephenOTT]

Consider scenario to add the variable values as form properties. So we can send only parts of variables: such as a Json object and we only want to send a specific property into the following form rather than the entire Json object.
