kolla bp/swift-container: Fix up supporting swift container functionality

[James McCarthy]

Background info, as part of review of: https://blueprints.launchpad.net/kolla/+spec/swift-container

Outstanding actions (considered techdebt against this blueprint) were originally captured in etherpad.

Main points in this regard seem to be:

investigate rsync
verify the remaining containers are functioning correctly: (auditor/replicator/updater/expirer)
    swift-object-auditor complaints ... STDERR: error: [Errno 1] Operation not permitted
    swift-object-expirer complaints ... UnexpectedResponse: Unexpected response: 400 Bad Request

    Add rsyncd image and related Ansible for Swift

    Swift replicator services require rsync to function. This patch adds a
    new container which is included automatically on each of the Swift
    storage nodes.
