support: remove ssh manipulation routes

this is now moved entirely to cloudron-support --enable-remote-access.

this emphasizes more that users have to get ssh access to the server before
we can do anything about it. it's far too simple for people to click this
button.

we have now also added clear terms to understand what remote access entails.
(what happens if support personnel makes a mistake. who is liable? etc)
