Add options to websocket gateway

[derzkiy]

For situation when you do not want send status information to all connected clients. But I'm not sure that this is the right way to configure websocket gateway decorator.

Hi @derzkiy, I really like your idea and I would like to thank you for your contribution. I think that we should add this feature to the library. But I don't think that user should set parameters through configuration of application. It should be done through configuration of module. I am not sure, at the moment, how that can be done.

I will do some investigation when I got some time next week.

Hi @ivanvs How are your investigation? Do we have any options to do that? I understand that approach is not so convenient, but it give us the way to set websocket options at least.

Currently we can't do it at all

I tried to find solution for this issue, but I still don't have solution that I am satisfied with.
