Ignore ssh keys, change input exceptions

Now input ssh has configuration secure which is false by default,
meaning we don't care about changing keys. It breaks ssh security model
but rancid does it too.

Also input models error handling is now mostly moved to node.rb for
centralized handling + logging. With input models only defining which
errors they want to receover from.
