upstream: add a ssh_config KnownHostsCommand that allows the client
to obtain known_hosts data from a command in addition to the usual files.
The command accepts bunch of %-expansions, including details of the
connection and the offered server host key. Note that the command may
be invoked up to three times per connection (see the manpage for
details).
