* MM-21012: Revamp websocket implementation We replace the old gorilla/websocket implementation with the gobwas/ws library. The gorilla library was in maintenance mode and had a high level API due to which we cannot use that for situations where a large number of concurrent connections needs to be supported. The ws library is a very low-level library that allows us to work with raw net.Conns. We make several improvements: - We completely remove the reader goroutines, and instead replace them with a manual epoll implementation which sends off messages to be read when it receives any data on the connection. This lets us scale to a much larger number of connections. - The reader buffer is eliminated, because we directly read from the connection now. https://mattermost.atlassian.net/browse/MM-21012 ```release-notes Improved the websocket implementation by using epoll manually to read from a websocket. As a result, the number of goroutines is expected to go down by half. ``` * fix tests * fix shadowing errors * final changes * windows support! * Remove pointer to waitgroup * Fix edge case * Trigger CI * Trigger CI Co-authored-by: Mattermod <mattermod@users.noreply.github.com>
