Running KDC as non-root and dockerize KDC

[Yegui Cai]

Hi all.

This can be two threads but I have the following two questions at the same
time.
1. Can we run KDC as a non-root user? Meaning is it required to run KDC as
root?
2. Is there any official docker images for KDC? or any plan to have one?

Thanks!
