docs: Checks if the given JSON contents are equal. The third parameter
  specifies whether exact string match should be used or diffing by the
  JSON objects ie. the order of the attributes does not matter.
  
  `from` and `to` can be either URI or the actual JSON content.
  
  You can add optional method (ie GET, POST, PUT), data or content type as parameters.
  Method defaults to GET.
  
  Example:
  | Json Should Be Equal | http://example.com/test.json | http://foobar.com/test.json | true |
  | Json Should Be Equal | { element: { param:hello, foo:bar } } | { element: { foo:bar, param:hello } } | true |
  | Json Should Be Equal | { element: { param:hello, foo:bar } } | { element: { foo:bar, param:hello } } | true | POST | {hello: world} | application/json |
