resource app adapter

* now using `binding.ResourceAppAdapter` to obtain any request related
`resource.Resource` option (resource, actual args, etc.)
* configurable pipelines for operations. Now remove add or any other
operation defined in pipeline mode and can be confgured by `LDPApp`,
`URIRefBinding` or `resource.Resource` class itself
* minor refactoring
