cluster/tier: add tunable to migrate files based on size
This fix adds a paramater "tier-max_promote_size" to control wether a file is migrated or not based on its size. By default the value is 0, meaning all files are migrated. If set to a non-zero value, files larger than the parameter won't be moved in tiered volumes.
