Make generate JSON Schema compatible with react-jsonschema-form?

[arildm]

We want to use the sparv schema output to generate a config form in Mink, but some details seem to be missing to be able to properly generate form components.

I pasted the schema at the react-jsonschema-form playground and got some errors:

• "Missing items definition" where the type is array
• "Unknown field type undefined" in some places

Note: I don't know yet if react-jsonschema-form is the lib we will want to use for this.

It doesn't seem to like when the datatype is undefined (including the datatype of items in an array). We don't require explicit datatypes in the Sparv config currently, and sometimes you actually want to allow any type of data, which is represented in JSON Schema by NOT specifying the datatype. I'm not sure how to best solve this.
