Undercloud Control element
public interface should be eth1
Sync with upstream changes for service-password
Add element for leaf node
Add iptables rule for mysql
Metadata updates
Fix syntax error
Remove ucl0 interface
Add hook to create needed directory for ssh key
Networking config updates
Configure quantum in nova.conf
Merge branch 'latest' into 2-node
Add leaf.sh to install a leaf node.  install.sh is modified to just install a
control node.  There is still a lot of code duplication between the two that
can be refactored out.

The long term idea is that install.sh will be just for the control node, and
leaf.sh will be just for the leaf.  If you want an all-in-one, you'd run both.
Adding more suport for leaf node.
Use 2-node branch of undercloud-live
leaf.sh should be +x
Add seperate scripts for control and leaf nodes.
More leaf support
Make os-config-applier run earlier on the leaf node too
Install iptables-services
