Andy McCrae 4aa96a832c Set rsync to not perform reverse lookups
We don't setup hosts entries for replication addresses on storage hosts,
by default. Rsync is performing a reverse lookup on each rsync, and
failing. We should turn this reverse lookup off by default, but allow
this to be set to True.

This PR adds the "swift_rsync_reverse_lookup" boolean which is defaulted
to false.

features:
- The ``swift_rsync_reverse_lookup`` option has been added. This setting
will handle whether rsync performs reverse lookups on client IP
addresses, and will default to ``False``. We recommend leaving this
option at ``False``, unless DNS or host entries exist for each swift
host's replication address.
upgrade:
- The default behaviour of rsync, to perform reverse lookups, has
been changed to ``False``. This can be set to ``True`` by
setting the ``swift_rsync_reverse_lookup`` variable to ``True``.
