mgr/dashboard: TCP port does not change when SSL is disabled
Florian raised a good point on IRC today:
<fghaas> So, it appears that if I do "ceph config set mgr mgr/dashboard/ssl false", then HTTPS is indeed disabled, but the service continues to listen on 8443, which strikes me as contradicting http://docs.ceph.com/docs/nautilus/mgr/dashboard/#host-name-and-port (which says 8443 for HTTPS, 8080 for HTTP).
<fghaas> To get the dashboard to listen on 8080, I also have to do "ceph config set mgr mgr/dashboard/server_port 8080".
When enabling/disabling SSL, it makes sense that the TCP port changes automatically accordingly, if the user did not explicitly choose a different one than the built-in defaults (8080/8443).
