Balazs Gibizer d38b7e13a6 Support sys.argv in wsgi app ...

At least uwsgi supports passing command line arguments to python wsgi
apps by specifying them as --pyargv for to uwsgi binary. Then the wsgi
app can access them normally via sys.argv.

This patch makes sure that nova-api and nova-metadata-api passes
sys.argv to oslo.config and therefore specifying config files for
these services now possible.

For example the following line in the systemclt service file makes sure
that the nova-api service reads both the nova.conf and the
nova-extra.conf

ExecStart = /usr/local/bin/uwsgi --procname-prefix nova-api \
  --ini /etc/nova/nova-api-uwsgi.ini \
  --pyargv "--config-file=/etc/nova/nova.conf
    --config-file=/etc/nova/nova-extra.conf"
