This PR updates the annotations for lua-resty-websocket, adding docstrings and parameter definitions from the repo. The objects created by
resty.websocket.serverandresty.websocket.clientare almost the same, so I factored out a lot of the common methods/fields into a class atresty.websocket.I'm new to writing EmmyLua annotations for this language server and don't understand everything yet, so please let me know if there is anything that I should fix regarding formatting, naming conventions, etc. (I think it would be great if there were a contribution/style guide for 3rd party type definitions, to encourage other folks in the community to pitch in).
I do a lot of work on OpenResty, so if you like this PR I will probably follow-up with more :)
