Add FUSE node fields to support multiple nodes with same name

The following new fields are added on FUSE node:
1. transforms: Flags determining what, if any transformations should
be done to the node
2. io_path: Allows re-directing path to use for actual IO different
from node->BuildPath()
3. io_ready: Allows lazyily transforming a node before accessing the
new io_path

These fields have default values and change should be a no-op

Test: Manual && fsstress for ~24hrs
