Allow multiple users to run Docker rootless

[daks]

Hello,

if I understand correctly the code, currently it only allows configuring one user to run Docker rootless.
I would like to be able to run a list of users. I think running rootless containers with different users may be a way to improve security further (no access to each other files for example).

Do you think it could be added?

Hi @daks, good idea. I'll have a look and see how it can be achieved.
