swift replication network should not be required

[Andy McCrae]

Since the galaxy role changes this bug has been re-introduced.

The replication network has to be specified which shouldn't be the case, and if the replication network is the same as the storage network it will cause failures.

    Ensure replication_network is not required for swift

    * Adjust config location variables for account, container, object
    variables, to name them more clearly.
    * Adjust config placement order, to happen after init scripts are
    created so that the service restart handler will work appropriately.
    * Ensure the init scripts for the replicator service are created
    appropriately whether a dedicated replication_network is or isn't used.
    * Ensure the dedicated replication network configuration is only created
    when replication_network is specified and different to storage_network.
    * Ensure the appropriate configuration section in the server.conf is
    only added when the replication_network is specified and different to
    the storage_network.
