cluster/dht/rebalance: rebalance failure handling
At current state rebalance aborts basically on any failure
like fix-layout of a directory, readdirp, opendir etc. Unless it is
not a remove-brick process we can ignore these failures.
Major impact: Any failure in the gf_defrag_process_dir means there
are files left unmigrated in the directory.
Fix-layout(setxattr) failure will impact it's child subtree i.e.
the child subtree will not be rebalanced.
Settle-hash (commit-hash)failure will trigger lookup_everywhere for
immediate children until the next commit-hash.
Note: Remove-brick opertaion is still sensitive to any kind of failure.
