Eve-log filetype redis do not support password configuration

When redis is select as eve-log filetype, we can not configure a password for redis client. Maybe we can add password configuration for redis filetype.

There is some work on this in a pull request: redis: Add authentication support v4 by AmazingPP · Pull Request #14002 · OISF/suricata · GitHub

Currently, it’s waiting on me to do another round of testing.

I now got it, thank you!
