cluster/afr: Hybrid Halo mounts
Summary:
- Implements "Hybrid" halo mounts which perform write FOPs synchronously
to all regions and read FOPs asynchronously to those nodes within the
region.
- Leverages the fact that the inode cache stores "hints" as to the
clean/dirty state of upto 16 replicas in the cluster; upon refresh of
an inode we can do a fresh lookup to get a "wise" node if none exist
in our region
- Activated via the cluster.halo-hybrid-mode option
Test Plan:
- Run AFR prove tests
- Run halo prove tests
