Upgrade async-tungstenite to v17 and update usage accordingly (#15219)
This PR upgrades `async-tungstenite` to v17.0.3. We previously attempted upgrading `async-tungstenite` in #15039, but broke authentication with collab in the process. Upon further investigation, I determined that the root cause is due to this change in `tungstenite` v0.17.0: > Overhaul of the client's request generation process. Now the users are able to pass the constructed `http::Request` "as is" to `tungstenite-rs`, letting the library to check the correctness of the request and specifying their own headers (including its own key if necessary). No changes for those ones who used the client in a normal way by connecting using a URL/URI (most common use-case). We _were_ relying on passing an `http::Request` directly to `tungstenite`, meaning we did not benefit from the changes to the common path (of passing a URL/URI). This meant that—due to changes in `tungstenite`—we were now missing the `Sec-WebSocket-Key` header that `tungstenite` would otherwise set for us. Since we were only passing a custom `http::Request` to set headers, our approach has been adjusted to construct the initial WebSocket request using `tungstenite`'s `IntoClientRequest::into_client_request` and then modifying the request to set our additional desired headers.
