Change websockets to use react-use-websocket package

[tjeerddie]

• remove custom websocket code.
• change websocketService to use the ws package and implement conditional Oauth.
• add setupProxy to be able to proxy orchestrator and cim.
• add filter to the proxies of /ws so the hotreloading doesn't break in development env.
• update useRunningProcesses and engineSettingsProvider to use the new websocket service.
