Service upgragre breaks admin user's passwords

[juanluisbaptiste]

Hi,

After doing a modification to my traefik install I got locked out of the traefik admin interface. Upon investigation I noticed that all the $ symbols in the hash string had been doubled. For example, for a password hash like this one added on an initial traefik install (throgh rancher catalog):

admin:$apr1$a7d3ipZE$bE2wACcJNGzjAd07iJq8o1

If the configuration is updated later, the hash will be saved like:

admin:$$apr1$$a7d3ipZE$$bE2wACcJNGzjAd07iJq8o1

If you save again it will add another $ and so on. Removing the extra $ symbols and saving fixes the lock-out.

This is on latest traefik 1.5.4-rancher1 available at rancher catalog on rancher 1.6.16.
