Description
Title: When an xDS update removes a cluster, any stats that get updated after the most recent sink or scrape will get dropped when the ScopeSharedPtr held in the cluster gets dropped.
Description:
To avoid this we should delay the destruction of the Scope for some time interval, perhaps a few minutes. We must be careful to accelerate the Scope destruction when the stats store gets destructed (server exit, or unit-test completion).
