### Do you want to request a *feature* or report a *bug*? feature ### Description Could we imagine an option to store the letsencrypt certificates as `.pem` files instead of (or next to) the `acme.json` file? This would be very useful to be able to directly reuse certificates in other non-web applications that rely on TLS (eg. [synapse](https://github.com/matrix-org/synapse) or [prosody](https://prosody.im/)). At the moment, a workaround could be to use the [`dumpcerts.sh`](https://github.com/containous/traefik/blob/master/contrib/scripts/dumpcerts.sh) script that you provide, and to call it with a *systemd.path* monitoring service (eg. something like http://www.ocsmag.com/2015/09/02/monitoring-file-access-for-dummies/ ). But having træfik directly producing the right output would be neat. thanks for the work on træfik!
