Merge lp:~bloodearnest/canonical-identity-provider/hi-fi-logging into lp:canonical-identity-provider/release

[Simon Davy]

Use the new logging library, talisker:

https://code.launchpad.net/~bloodearnest/+junk/talisker

This library aims to standardise logging across our services, as well as provide structured logging. It does the following

 - a standard log format
 - arbitrary key=value pairs
 - log to stderr, for the charm to handle files, directories and perms, etc (12 factor app)

This change:

 - uses the gunicorn wrapper for make run, which sets up logging
 - disable django's default logging, as it's not needed any more (and has bad production defaults, see https://docs.djangoproject.com/en/1.8/topics/logging/#default-logging-configuration )

For that makefile rule, yes. The defaults are production orientated,
and thus silence python's warning system (which is also what django's
default logging did before). --devel logs the warnings, which is what
we want in development, when this make target is designed to be used.

Thanks
