    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.
