@Hexiaoqiao @ayushtkn @tomscut , could you please help review this patch?
This change introduces a configurable cap on checkpoint fsimage upload
concurrency.
It targets deployments (for example, 2 NameNodes + 9 Observers), where
unconstrained parallel upload can create too many concurrent transfers.
With this cap, we can keep parallelism while preventing excessive upload
pressure.
> Limit fsimage transfer concurrency during checkpoint with multiple NameNodes.
