[IMPROVEMENT] All logs are displayed in UTC timezone and cannot be changed

[Lenny Primak]

Currently, all logs, including in the UI are displayed in UTC. This is not user-friendly.
I would like to see the logs in the UI displayed in User's timezone.
For example, I used k8tz (https://github.com/k8tz/k8tz) to set Longhorn's pod timezone
to America/Chicago. I would like Longhorn UI to respect this setting.
This is especially confusing for Asia, since not only times, but dates are wrong most of the time.

I do understand that Longhorn currently assumes that all logs are in UTC, making things a bit complex
