Add a test to ensure the version check error

_LC wasn't imported with the other log translation methods. This section
of code was untested. We should enforce the behaviour to handle changes
in this area.

Allow loading other auth methods in auth_token

Add handlers for loading user specified authentication plugins from the
config file. If an auth plugin is not specified then we fall back to
using the older legacy options.

Use newer requests-mock syntax

You can specify mocks in requests-mock using the method name as the
function rather than having to repeat strings throughout code. This
makes it less likely you'll make a simple mistake and looks cleaner.
