[GSS](7.0.z) RESTEasy returns wrong Content-Encoding data if client request gzip

By default, RESTEasy returns wrong Content-Encoding data if client request gzip data and if RESTEasy end-point contains @GZiP annotation

1. Server contains end-point with @GZIP annotation, for example this:

       @GET
       @Path("/echo")
       @GZIP
       String echo(@QueryParam("name") String message);

2. RESTEasy client send request with "Accept-Encoding: gzip, deflate"
3. By default, server doesn't use GZIPDecodingInterceptor, GZIPEncodingInterceptor and AcceptEncodingGZIPFilter. So server doesn't compress data
4. server sends "Content-Encoding: gzip" in header of response, although data is not compressed
