Handle uwsgi on systemd properly

Browse Source 
uwsgi is a different service type under systemd and shouldn't be run as
a standard oneshot type. The uwsgi docs outline a good pattern for
writing systemd unit files:

http://uwsgi-docs.readthedocs.io/en/latest/Systemd.html

This commit takes those suggestions and creates a separate path for
writing uwsgi unit files.
