HttpRequest::getParameters() missing query parameters if URL ends in path parameter

**Describe the bug**
If you register a HTTP method using an URL format like DELETE "/v2/hello/{path_param}" and call it like this:

DELETE /v2/hello/world?param1=abc

then httpRequest->parameters() returns a std::map containing only "path_param" = "world" and it is missing "param1" = "abc"

**Expected behavior**
The httpRequest->parameters() Method should return ALL parameters that were passed to the method. Or there should be a seperate API to query path params and query params.
