CLDSRV-827: Fix contentLength and objectSize in access logs

[dvasilas]

The contentLength field in S3 analytics captures egress (response size) for GetObject operations and ingress (request size) for PutObject.

In server access logs, contentLength was the HTTP request body size (bytes received from client).
This broke backwards compatibility with S3 analytics, and caused an Integration test to fail.

---

The fix is to update contentLength to capture transfer size (egress for GET, ingress for PUT).

This PR includes a second fix for objectSize to always reflect full object size (and not sizes in range get operations).
