refactor: Migrate retry handeling form backoff to tryhard
fix: retry 502 status without delay in control connection
At some sites the status code returned by the proxy on timeout is 504 instead of 502 leading us to wait a minute before trying to reconnect.
But because 502 might also indicate a permanent problem with the network we don't want to spam the proxy as fast as possible with requests which is why I introduced a counter which keeps track of how many times we hit such a status code and if its more than 10 times in the last minute we retry only every minute.
