Title: Remove pson document type

This removes the encapsulation in the PSON serialization format. Puppet only did this when using PSON on certain endpoints, other formats like YAML or MsgPack never did this.

This is backwards compatible with older Puppet versions as they throw away the info if it is there. But it is backwards incompatible for other consumers of the PSON APIs.
