Replace builtin SSL redirection with manual one (#415)

As outlined in this (traefik/traefik#1957)
issue SSL redirection with PathPrefixStrip does not work really well.

A solution was provided in this (traefik/traefik#3631) PR,
released in 1.7, but it didn't really solve the issue.

In fact, there were several subsequent issues opened
(traefik/traefik#3999, traefik/traefik#3876)
but they got closed.

Another issue was opened in the Traefik repo: traefik/traefik#4085

Until then this workaround provides the same functionality.
