Fix swift-ring-builder ordering

Tie ring_*_device resource to ring_devices resource
by setting autorequire, thus making ring_devices resource
run after ring_*_device and ensure it is before rebalance
anchor

How to test:

1) install swift binaries

2) run:
rm /var/lib/puppet/state/graphs/* && puppet apply --graph -vd
--modulepath /home/vvk/git/fuel/deployment/puppet/ -e
'anchor{"rebalance_begin":} Ring_devices<||> ->
Anchor['rebalance_begin'] ring_devices{'all':  storages=>
[{"storage_address"=>"10.10.10.10"}] }'

3) read /var/lib/puppet/state/graphs/relationships.dot

The purpose is to set all ring_*_device before
Anchor['rebalance_begin']
