[SRU] octavia-api won't start by default

[Corey Bryant]

[Impact]

After installing octavia-api the systemd unit fails to start:

Failed 'systemctl status octavia-api' output shows:

error: unrecognized arguments: --http-socket [::]:9876 --ini /etc/octavia/octavia-api-uwsgi.ini

The problem is that init files are configured with UWSGI options but the binary being run is not uwsgi. See full output: https://paste.ubuntu.com/p/WHQk2y2F84/

[Test Case]
1) sudo apt install octavia-api
2) watch systemctl status octavia-api # watch to ensure it doesn't fail
3) curl 127.0.0.1:9876 # should return something like [1], not [2]

[2] curl: (7) Failed to connect to 127.0.0.1 port 9876: Connection refused

[Regression Potential]
Low. The provided fix only touches the octavia-api and is using the standard approach that OpenStack has historically used to start a service which is to use the service's /usr/bin/<service>-api file which in the case of octavia is using wsgiref.simple_server to host the API WSGI server. Ideally we'll like to run the API under an apache2 server but that switch seems more appropriate in a development cycle than a stable cycle.
