[PULL 03/46] python/qemu: qmp: Make accept()'s timeout configurable

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

From: Wainer dos Santos Moschetta <wainersm@redhat.com>

Currently the timeout of QEMUMonitorProtocol.accept() is
hard-coded to 15.0 seconds. This added the parameter `timeout`
so the value can be configured by the user.
