ssh: log the libssh2 error message when ssh session startup fails
When a ssh session startup fails, it is useful to know why it has failed. This commit changes the message from: "Failure establishing ssh session" to something like this, for example: "Failure establishing ssh session: -5, Unable to exchange encryption keys" Closes #3481
