Add configuration option whether Ditto should generate condition "property bag" notation for WoT TDs

[thjaeckle]

Ditto currently generates TDs in a way to also generate (some) supported query params by Ditto.

Example:

...
"forms": [
        {
          "op": "readproperty",
          "href": "attributes/location{?channel,timeout}",
...

Where "channel" and "timeout" are defined as well as "uriVariables" in the TD.

While this is specified in the standard it often happens that tools cannot handle this "strange" syntax of URIs - so I would propose making it configurable to generate those - and maybe even deactivate it by default.
