This PR implements locking from a global entity into a more localized set level entity, allowing for locks to be held only on the resources which are writing to a collection of disks rather than a global level. In this process this PR also removes the top-level limit of 32 nodes to an unlimited number of nodes. This is a precursor change before bring in bucket expansion.
