Add procname for uwsgi based services

Code in grenade and elsewhere rely on the process/service name
when one runs "ps auxw" and they grep for example "grep -e glance-api"
to check if the service is running. with uwsgi, let us make sure
we use process name prefix so it is easier to spot the services
and be compatible with code elsewhere that relies on this.
