Docker's provider drops a container's own docker-label routers when
Docker reports that container unhealthy. --ping=true had been dropped
somewhere along the way, so /ping 404'd, the healthcheck failed,
traefik was marked unhealthy, and its own traefik-dashboard-web(-secure)
routers disappeared as a result. Also restores acme.tlschallenge=true
(needed for cert renewal) and drops the debug log level used for
earlier troubleshooting.
