Multi-Site Setup with and without bucket sync policies

This document goes over the different use cases of bucket sync policies and zone level multi-site object setup.

Zones: Three zones are depicted: us-east1 (Primary), us-west1 (Secondary), and us-west2 (Secondary).
Primary to Secondary Replication:
- If "symmetrical replication" is chosen, default "enable" rules exist between the primary and each secondary zone.
- If "bucket level replication" is chosen, default "deny" rules (default-deny-us-east1-us-west1, default-deny-us-east1-us-west2) are created in "allowed" state, meaning they prevent replication until specific bucket rules are added.
Secondary to Secondary Replication:
- No default deny rules are created between secondary zones (e.g., default-deny-us-west1-us-west2 is not automatically created).
- To sync buckets between us-west1 and us-west2, a specific "enable" rule like enable-us-west1-us-west2 needs to be manually created. This rule is directional and only applies to specific buckets once bucket-specific rules are added.

Note : While the AWS replication feature allows bucket replication within the same zone, RGW does not allow it at the moment.

Multi-site is setup with full zone replication selected.

Multi-site is setup with full zone replication selected for us-east-1 and us-west-1.

Multi-site is NOT setup with full zone replication selected for us-east-1 and us-west-2, selected buckets need to have sync policies.

In addition there are bucket sync policies between the two secondary zones (us-west-1 and us-west-2)

us-east-1 and us-west-1 has two storage classes STANDARD and STANDARD_IA

us-west-2 only has STANDARD
