[fix][broker] Immediately tombstone Deleted and Free state bundles and enable MultiPhaseBundleUnload for non-transfer unloading
Motivation
-
Extensible Load Balancer cannot split bundles when a namespace is recreated. The old parent bundle before split (in the Deleted state) could block the next split operation until they are tombstoned by the leader monitor bundle cleanup job.
-
Extensible Load Balancer delays bundle cleanups when a namespace is deleted. Those deleted bundles are stuck in Free state until they are tombstoned by the leader monitor bundle cleanup job. Although this delayed tombstone was introduced for non-transfer unloading, these lingering bundles are not ideal when the namespace is deleted.
-
Extensible Load Balancer does not enable MultiPhaseBundleUnload for non-transfer unloading. Realized that we could enable MultiPhaseBundleUnload for the non-transfer unloading as well for more graceful unloading, as per pip-307(e.g. make sure to close ledgers before lookup).
