Define unique hostname for QManager

Browse Source 
Due to the shortcoming of QManager implementation [1], in case of uWSGI
usage on metal hosts, the flow ends up with having the same
hostname/processname set, making services to fight over same file
under SHM.

In order to avoid this, we prepend the hostname with a service_name.
We can not change processname instead, since it will lead to the fight
between different processes of the same service.
