Title: (#16134) Quote class names inside relationships

Prior to this commit, the chaining resource relationship syntax
used in several of the apache::mod::* manifests specified class
relationships without quoting the class names. Apparently, this
broke the parser in Puppet 2.6.x. This commit wraps those class
names inside single quotes, making the 2.6 & 2.7 parser happy.
