Added a few more attributes to override for LAMP.
Set rs-application_php/application_name since LAMP not used in load balancer.
Removed the override of rs-mysql/server_repl_password since its nonexistence will be handled by rs-mysql::default recipe.
rs-application_php/application_name cannot have dashes.
Update tests to match changes to default recipe.
