URL: https://github.com/apache/ozone/pull/9472
## What changes were proposed in this pull request?
This PR updates existing SCM `ReplicationManager` to capture all container
replication statuses in existing `ContainerInfo` object. The implementation
uses a simple enum-based approach with short values, enabling SCM to track
both individual health states (e.g., `UNDER_REPLICATED`, `MISSING`) and common
combinations (e.g., `UNDER_REPLICATED_MIS_REPLICATED`) efficiently.
**Key Features**
1. `ContainerHealthState` Enum
- Individual states (values 0-99): 11 health states including `HEALTHY`,
`UNDER_REPLICATED`, `MIS_REPLICATED`, `OVER_REPLICATED`, `MISSING`,
`UNHEALTHY`, `EMPTY`, `OPEN_UNHEALTHY`, `QUASI_CLOSED_STUCK`,
`OPEN_WITHOUT_PIPELINE`, and `REPLICA_MISMATCH`
- Combination states (values 100+): 8 common combinations like
`MISSING_EMPTY`, `UNDER_REPLICATED_MIS_REPLICATED`, etc.
2. `HealthStateFilter` API
- Simple filtering mechanism for querying containers by exact health state
match
- Factory methods: `HealthStateFilter.of(state)` for single state or
multiple states
- Clean matches() method for container filtering
3. `ContainerInfo` Integration
- New healthState field (short, 2 bytes per container)
- New healthStateUpdateTime field for tracking when health state changed
- Automatic timestamp updates when health state is modified
- Protobuf serialization support
4. `ContainerManager` Query API
```
List<ContainerInfo> getContainersByHealthState(HealthStateFilter filter);
Map<ContainerInfo, ContainerHealthState>
getContainersWithHealthState(HealthStateFilter filter);
```
## What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-14119
## How was this patch tested?
This patch is tested using new test cases:
`TestContainerHealthState` covering:
- All individual states and combinations
- Conversion from ReplicationManager states
- Protobuf serialization/deserialization
- Health state filtering and querying
- Edge cases and invalid states
