Adding filenames from the zip to the response for httpjson

[kgeller]

What does this PR do?

The httpjson input will report filenames for application/zip events in the response.

Why is it important?

We have a bug for an integration that utilizes the filename to determine a log_type field as the field is in the name. For example, filename="delivery_20160705162902600.log" -> log_type: delivery. When utilizing compress: true, the filename is instead a random guid and so the log_type can't be derived, example filename="8578FCFC-A305-4D9A-99CB-F4D5ECEFE297.zip".
