The release scripts had been assuming that a valid gerrit user was
always configured already, but this is not necessarily the case on all
nodes. Now that the constraint update job has moved to the proposal
nodes, we need to make the cloner code try to configure the gerrit user
if "git review -s" fails. We can't always take that step because it
would result in using the wrong user on the signing node and when users
run the scripts by hand (as we still do frequently to recover from
failures).
