Update led-manager to use JSON

Current LED manager uses compile time generated led-gen.hpp and creates
DBus objects for the groups.
We would need this changed to use the generated JSON.

Tested: JSON used at runtime when --enable-json given at configure time.
led-gen.hpp not created when using JSON and led-gen.hpp created by
default when using YAML at build time.
