Having a separate vnode_worker_pool wouldn't reoslve he parallelism issue obviously! Need a node_worker_pool instead.

Update thoughts on concurrency management
...
After reviewing the code it looks easier to have separate pool of vnode
workers to manage concurrency, rather than trying to alter the coverage
FSM itself. This will make it easier to adjust for different backend
capabilities (i.e. worst case it would fallback to unthrottled).

Returning bucket when bucket is all

Need to know {Bucket, Key} not just Key if all buckets are being covered
by nrt aae. So shoehorning this in - will also allow for proper use of
FilterFun when filtering by partition.
