manager: utils: timeout fix for unix-socket http request
I found a bug that was causing random failures in CI pkg tests. It was caused by the unix-socket connection timeout which was hardcoded to 1 second. The timeout was hardcoded because there was some problem with self.timeout in the past, comment "# there is something weird stored in self.timeout". I haven't found a problem with self.timeout. I'd say it's related to old versions of Python that we no longer support.
