Lambda function which automatically sets a destination for all newly created Cloudwatch Log groups. When a subscription filter is modified or deleted, the function will add back the expected subscription filter. In the case there are two subscription filters already, the last one is deleted.
This allows us to centralise all of our logs into a single account.
