ACS-2222 Add ArchivedIOException (#802)

`ArchivedIOException` and `ArchivedContentException` added to provide an appropriate response when attempting to access content that is archived, for example in GLACIER s3.

Discovered and fixed a bug, when producing an error during content streaming that caused clients to hang. Content Length now set to `-1` when any `ContentIOException` is thrown so that any clients are not expecting and waiting to received the content.
