Reviewer Andy: Extra tweaks to AMI creation
Use new schema
Only specify enum_server if one is configured for this environment
Reduce TTL for cluster DNS records to 60 seconds
Write cluster_settings file during clustering
Open memcached interface port 11211 between sprout nodes (and remove Infinispan ports)
Write cluster_settings file during clustering
Remove infinispan clustering support as the code isn't safe for a node that doesn't have infinispan installed
Specify port explicitly in memstores - for some reason libmemcached is a bit tempermental with it
Cookbook changes to handle memcached cluster settings
