* Add BulkDump/BulkLoad observability for backup/restore progress tracking
Progress tracking APIs:
- getBulkDumpProgress() / getBulkLoadProgress() - track tasks, bytes, throughput, ETA
- getBulkDumpOwner() - track job ownership (e.g., which backup owns a bulkdump)
- Owner registration system for backup agents
CLI improvements:
- 'bulkdump status' and 'bulkload status' commands with human-readable output
- Progress display with throughput and ETA
Backup agent integration:
- Register backup as owner of bulkdump jobs
- Show bulkdump/bulkload progress in backup status output
Utility functions (flow/Util.h):
- formatBytesHumanReadable() - "1.23 TB", "456 MB"
- formatDurationHumanReadable() - "2 hours 30 minutes"
- formatBytesProgress(), formatThroughputLine(), formatETALine()
Test coverage:
- verifyBulkDumpObservability() / verifyBulkLoadObservability() in BackupS3BlobCorrectness
Bug fixes:
- Fix format string mismatch crash in FileBackupAgent progress display
- Add empty result guards for krmGetRanges() calls to prevent size_t underflow
* Formatting
* Rebase and formatting
* * cmake/CompileRocksDB.cmake
Preserve version when find_packge doesn't turn up rocksdb version
* fdbbackup/tests/backup_tests_common.sh
Wait when mode is 'both' for snapshot to be written.
* fdbclient/BulkLoading.cpp
Remove extra '/'.
* Output time of bulkload in bulkload history fdcli output as iso8601 instead of seconds since epoch
* Print start time as iso8601 -- readable -- instead of seconds since epoch -- unreadable... And don't crash if not a UUID
* Remove cute graphics.. and bullet characters
* Throw exception if not able to parse backup 'mode'
