Before assuming that a certain host runs an SSH server, we now test its
`SSHPort` for connectivity. This means that the test `should be able to
run crictl on the node` can be now more failure proof by checking only
hosts where SSH actually runs. Beside that, we can also test all hosts
and not only the first one.
