Without this change, the end user of the module may run into issues
establishing relationships to the composite class (the main nginx class)
For example, the user may declare this relationship expecting
nginx to be managed after the yum repositories have been configured:
node default {
class { 'site::yumconfig': }
-> class { 'nginx': }
}
However, all of the resources exist in implementation classes, which
do not have a transitive relationship declared to the nginx class.
Without this change, Puppet may very well manage Class['nginx::config']
before Class['site::yumconfig'] even though the user clearly indicated
this should not be the case.
