Subject: [PATCH] [BUGS-7678] add PANTHEON_HOSTNAME to application.pantheon.php
 (#119) (#120)

* break up the PANTHEON_ENVIRONMENT conditional

so we can use the same one later for the new stuff we're adding

* define PANTHEON_HOSTNAME if it's not already defined

* add phpcbf command

* lint

* add our filter to update the config instructions
use Config::define instead of define

* return the contents

* apply changes from wp upstream
