REST: Add method return support for basic types

Add support for returning the basic D-Bus types,
such as int, string, etc, from methods.

It does this by using the sd_bus_message_read_basic
API to pull the data out of the method response message,
and then converts it to JSON.

Future commits will add array/dict/variant support.
