Comment 3 for bug 1748210

I performed the following tests so far:
- used a charm bundle to deploy a complex application that uses haproxy as the frontend, with and without ssl (landscape-server). Added backends after the deployment as well. Worked as expected
- tried reload while there were ongoing live connections to the backends via haproxy. Saw the new -x option be automatically used, and once the connections ended, the old haproxy processes disappeared.
- tried an upgrade from 1.7.x to 1.8.4 with a simple app (haproxy as the fe, one apache server as the be)
