SHOW BACKENDS header columns misaligned with data rows in 4.0.5 (CpuCores, Memory, LiveSince, RunningTasks, NodeRole)

[atifiu]

Version: doris-4.0.5-rc01-59de8c4c524

What's wrong: The header row of SHOW BACKENDS lists trailing columns in the order CpuCores, Memory, LiveSince, RunningTasks, NodeRole, but the data rows place values in the order NodeRole, CpuCores, Memory, LiveSince, RunningTasks. Result: CpuCores column shows mix, NodeRole shows 0, etc.

Reproduction: Run SHOW BACKENDS; on a fresh 4.0.5 cluster.
