Description

To allocate and share resources (block cache) between the RocksDB instances of multiple tasks and operators in a slot, we need a per-slot component to track these shared resources.

The MemoryManager is a good fir for that, because we also want to allocate these resources from the managed memory budget maintained by the MemoryManager.
