[CONSUL] Make consul run as non-root

Use our recently build consul image (still based on the same old
consul version) and modify the deployment to make sure that it is able
to run as non-root user.

Yes, I know that moving consul-server to component would be more
proper solution but as this commit is supposed to be cherry-picked to
guilin I've tried to make as little changes as possible.
