Review Comment:
@xichen01 so what is the way to go forward ? should we combine both and
adapt the concept of durability, SLA, zones, and latency , etc as below:
Add a second constructor arg. `GLACIER` gets null replication, meaning "no
replication opinion,
archive tier only" — AWS does not
pin storage class to a replica count,
and inventing one for `GLACIER` would make it indistinguishable from
STANDARD_IA on the reverse map.
```
REDUCED_REDUNDANCY(RatisReplicationConfig.getInstance(ReplicationFactor.ONE),
HOT),
STANDARD(RatisReplicationConfig.getInstance(ReplicationFactor.THREE),
HOT),
STANDARD_IA(new ECReplicationConfig(3, 2),
WARM),
GLACIER(null,
COLD);
```
