Openstack logging handler.
This module adds to logging functionality by adding the option to specify
a context object when calling the various log methods. If the context object
is not specified, default formatting is used. Additionally, an instance uuid
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.
It also allows setting of formatting information through conf.

A context.RequestContext aware formatter configured through flags.
The flags used to set format strings are: logging_context_format_string
and logging_default_format_string. You can also specify
logging_debug_format_suffix to append extra formatting if the log level is
debug.
For information about what variables are available for the formatter see:
