Ensure that logs include the function Alias as part of the message so we can correlate activity between different Lambda aliases.

Perhaps we should use an actual logging package (so long as it has the same end effect as console.log() because that's what Lambda expects to send to CloudWatch).

@mathomas I'd need some clarification here. The alias is already logged as a part of ARN at the beginning of each invocation, which btw has unique UUID, which could be used for corelation - isn't that enough? Would you rather see alias (PROD, TEST, etc.) per each line of log?
