Clement Sam f076238748 storagenode: run used-space filewalker as a low IO subprocess
As part of fixing the IO priority of filewalker related
processes such as the garbage collection and used-space
calculation, this  change allows the initial used-space
calculation to run as a separate subprocess with lower
IO priority.

This can be enabled with the `--storage2.enable-lazy-filewalker`
config item. It falls back to the old behaviour when the
subprocess fails.
