[pm-h] JSON vs JSON::PP vs JSON:XS between EL5 and EL6

[Reini Urban]

First: Switch to a proper JSON encoder, JSON::Any lists them from best to worst:

Cpanel::JSON::XS
JSON::XS
JSON::PP
JSON
JSON::DWIW

And for the sort feature, test it with Cpanel::JSON::XS and if does
not work file an interop issue with
https://github.com/rurban/Cpanel-JSON-XS/issues
The developer (me) is usually very responsive and it sounds like a
worthwhile feature.
Just a bit tricky to implement.
