Zach Brown 65c3ac5043 scoutfs: Add cluster locking to node/file ops ...

This gives us cluster locking for the overwhelming majority of metadata ops
that scoutfs supports. In particular, we can create and modify file metadata
from one node and immediately see the changes reflected on another node.

In addition to synchonrization the cluster locks here are providing an I/O
endpoint for our item cache, ensuring that it doesn't read stale items.

Readdir and file read/write are notable exception - they require a more
specific approach and will be implemented in a future patch.
