Restore assumed br-cli execution user to be root?

[wey-gu]

It seems br-cli assumed br-cli execution user to be root, otherwise, it failed during the phase of scp -r files_to_cluster_node.

I am not 100% sure if this is the root cause while when I was trying to reproduce the same scp call from the error(1), the only error I could reproduce is when I do it w/o root user and it complained permission was denied. And after I switch to the root user, it succeeded.

If this is the case, it could be improved by calling scp -r <backup> {user}@node:foo instead of the current scp -r <backup> node:foo, right as --user was specified already?

If this is not the case, please ignore it and close it, thanks :)
