JSON related utilities.
This module provides a few things:
1) A handy function for getting an object down to something that can be
JSON serialized. See to_primitive().
2) Wrappers around loads() and dumps(). The dumps() wrapper will
automatically use to_primitive() for you if needed.
3) This sets up anyjson to use the loads() and dumps() wrappers if anyjson
is available.

This module adds to logging functionality by adding the option to specify

may be passed as part of the log message, which is intended to make it easier
for admins to find messages related to a specific instance.
