Add logging stack trace on auth failure

[dbeliakov-r7]

When authentication fails, logger only saves the exception message. This is often not enough to understand what caused the failure.
This change adds the stack trace to the error message.

No, this is not the way to implement this.
You can simply add the exception as a third argument to the log method call.
I.e getLogger.log(Logger.WARN, ..., ee).

See

jsch/src/main/java/com/jcraft/jsch/Session.java

Line 1443 in d064f44

getLogger().log(Logger.ERROR, "start_discard finished early due to " + e.getMessage(), e);

for an example how to log the exception stack trace correctly.
