Unfortunately this breaks backward compatibility, but we have to do it,
because current order is totally wrong. Configuring user with `dvc
remote modify myssh user` is an explicit action and should have higher
priority than implicit url. This is also important, since in the next
patch in this PR we will introduce support for `port` configuration,
that should also follow the same logic.
