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.
