Support embedding variables in json files

[k2tzumi]

Proposal

To allow variables to be embedded in json files for more flexibility as test data.

{
    "code": "{{ vars.code }}",
    "data": {
       "foo": "test",
      "bar": 1
   }
}

Use vars syntax to expand variables when reading json.

Very interesting 👍

I think the following implementation might be difficult

• Expansion of Integer and Boolean types

Expansion of Integer and Boolean types

I think I was limited to only within a string to expand a variable, so this problem is difficult.

Other tools seemed to have the same problem. 😓
