We have a special logging formatter that is used to show info when a

django HttpRequest is part of the log record. Once upon a time, the

way of getting extra information into a log record was just to pass it

as additional kwargs to the log methods, but the modern, documented

way of doing it is to pass a single extra dict. This change fixes our

code up to use that. We also had several logging instances where we had

the request available but were not passing it to the log.
While I was auditing our log messages, I fixed up some other trivial

issues like formatting with args and indentation.

Ran unit tests.
