When building instance that uses cloud-init the phone home function uses a POST while the foreman routing only supports GET.

the cloud-init cc_phone_home script uses a POST to mark the end of a foreman build,

https://github.com/theforeman/foreman/blob/9b6c84d45289e83567752eb35e38edeaaafe9dc4/config/routes.rb#L430

but when this task is executed by cloud-init the following error shows in the foreman/production.log and the status of the instance in the foreman gui is "pending installation."
