[QA] misleading error messages when using sssh commands

[mcm1957]

When enebaling debug log shutdwon / reboot logs the following confusing error messages:

synology.0 | 2022-10-26 19:30:55.440 | warn | System reboot
synology.0 | 2022-10-26 19:30:49.076 | debug | *** ERROR : src: SSH Error: code: undefined message: Password:
synology.0 | 2022-10-26 19:30:49.010 | debug | *** ERROR : src: SSH Error: code: undefined message: Could not chdir to home directory /var/services/homes/testiob: No such file or directory
synology.0 | 2022-10-26 19:30:48.845 | debug | SSH:echo '******'\|sudo -S shutdown -r now
synology.0 | 2022-10-26 19:30:48.843 | debug | state synology.0.commands.reboot changed: true (ack = false)

The reason is, that ALL output returned by ssh at stderr is logged as error. BUT the password prompt is no error wat all. And depending on the synology setup the chdir error is no error too but caused by the fact that at this system no user homediectories existe (user home service not enabled)

If possible those misleading erros should be filtered.
