Contain all classes within Class[nginx]

This change uses the anchor relationship from the puppetlabs-stdlib
module to contain all of the module classes within the main "ntp" class.

Without this change, end users of the module may have difficulty
ordering things correctly since they will have to peek inside the module
and figure out it's internal workings to identify all classes that
require relationship edges.
