Contemplate/Fix automated Loggly configuration

[sopel]

See 8) in https://github.com/cityindex/logsearch-development-flow/issues/152#issuecomment-23421782 for the background.

It should be possible to drive that via the Loggly API instead, which is going to be required for a decent Auto Scaling setup.

• :exclamation: This is a bug, given that it isn't currently doing just that and we won#t have the desired log search functionality in place when we need it the most.

@dpb587 - the Configuration Mgmt page seems to provide all required information by means of a sample Python script:

Part of our security includes locking down the list of devices that are allowed to send data to your inputs. If you have a dynamic environment, however, the list of devices will likely change on a frequent basis. To help with this, we have a python script that will authenticate devices without requiring that you work through the Loggly user interface. Use this script with your configuration tool (e.g. puppet/chef) to auto-authenticate devices when you spin up a new instance.
