GROUNDWORK-3105 Handle oversized payload

[ymkins]

It addresses the issue caused by reaching 8MB limit for size of the message stored in Nats queue.
It's a rare case on huge inventory only.

We handle oversized payloads on quieing in a few steps:

• Compressing oversized payloads with GZIP before processing in qieue. Then sending gzip-compressed payloads on HTTP as we already support it.
• And huge payload that oversizes 8MB limit after compression processed in queue as a placeholder instead of data and stored as file.
