BZ #1087713 - Add Swift Proxy service to HA hostgroup.

https://bugzilla.redhat.com/show_bug.cgi?id=1087713

Add Swift Proxy to the HA-All-in-One-Controller.  Includes use of a
new quickstack::rsync::simple type which is needed vs. traditional
::rsync so as to bind to multiple addresses.  Also includes update to
the script ha-all-in-one-util.erb/bash which allows us to wait to add
cloned resources after services are present on all nodes.
Merge pull request #164 from cwolferh/ha_swift

HA Swift. rsync refactor.
