Refs: #3490106

updated pagecache-fix-3490106-7 to work with version 4.x

this includes:

• minor code style changes done by phpcs
• Added a haskey function to only check if a key is present and not return the key itself.
• added an override for the default page cache logic to not cache requests made using an apikey. (this would otherwise potentially expose authorized data to unauthorizeed users).
