contint: disable DNS lookup for castor rsyncd
The rsync server on castor is hit by the contintcloud disposable
instances. The wmflabs infrastructure does not always properly set the
DNS entry which causes /var/log/messages to be spammed by:
forward name lookup for
ci-trusty-wikimedia-x.contintcloud.eqiad.wmflabs failed:
Name or service not known
From rsyncd.conf:
forward lookup
Controls whether the daemon performs a forward lookup on any hostname
specified in an hosts allow/deny setting. By default this is enabled,
allowing the use of an explicit hostname that would not be returned by
reverse DNS of the connecting IP.
Since we do not rely on hosts allow/deny, disable the DNS forward lookup
entirely which would stop the log spam.
Bug: T136276
