Consider redact password included in jump-connect exception

If an error occurs during connection, the [exception thrown](https://github.com/clj-commons/clj-ssh/blob/7b075dbc46d010cfe42e85be988f69f069db94e7/src/clj_ssh/ssh.clj#L445-L446) includes the entire `hosts` list, which in turn may have passwords and those passwords will be present in the stacktrace.

```clojure
(fn [e s]
(throw
(ex-info
(str "Failed to connect "
(.getUserName s) "@"
(.getHost s) ":"
(.getPort s)
" " (pr-str (into [] (.getIdentityNames agent)))
" " (pr-str hosts))
{:hosts hosts}
e)))
```

The password could be removed from the exception message and data.

Start in src/clj_ssh/ssh.clj at lines 445-446 and inspect how the jump-connect exception uses hosts in its message and data. Done means the exception no longer exposes passwords in either the stacktrace message or exception data while retaining useful connection information.
