URL: https://github.com/apache/ozone/pull/8933
## What changes were proposed in this pull request?
This pull request introduces a new Ozone CLI command ozone admin namespace
rebuild that allows administrators to manually trigger a rebuild of the Recon
Namespace Summary data. The implementation adds both the REST API endpoint in
Recon and the corresponding CLI subcommand.
**Changes proposed:**
1. **New REST Endpoint**: Added POST `/api/v1/namespace/rebuild` endpoint in
`NSSummaryEndpoint` class that:
- Checks if Recon is properly initialized before proceeding
- Uses the existing unified rebuild control mechanism from
NSSummaryTask.RebuildState to prevent concurrent rebuilds
- Triggers asynchronous namespace summary rebuild via
ReconUtils.triggerAsyncNSSummaryRebuild()
- Returns appropriate JSON responses indicating rebuild status (STARTED,
IN_PROGRESS, FAILED, etc.)
2. **New CLI Subcommand**: Implemented `RebuildSubCommand` class that:
- Makes HTTP POST request to the Recon rebuild endpoint
- Provides clear, feedback about rebuild initiation status
- Handles error scenarios (connection failures, authentication issues,
server unavailability)
3. **CLI Integration**: Added the new subcommand to
`NSSummaryAdmin.subcommands` array to make it available as ozone admin
namespace rebuild
