Python Proxy.myproxyValidity方法代码示例

        usercertDaysLeft: the number of days left before your user certificate expire

        If we need to renew the proxy in myproxy because its atributes has changed or because it is valid for
        less time than timeleftthreshold then we do it.

        we delegate the proxy just for the time we need (checking first if we did not already do it since at some point
        usercertDaysLeft ~= myproxytimeleft and we don't need to delegate it at every command even though myproxytimeleft < timeleftthreshold).
