    rgw: change json formatting for swift list container
    
    Fixes: #4048
    There is some difference in the way swift formats the
    xml output and the json output for list container. In
    xml the entity is named 'name' and in json it is named
    'subdir'.

    java: make CephMountTest use user.* xattr names
    
    Changes to the xattr code in Ceph require
    a few tweaks to existing test cases.
    Specifically, there is now a ceph.file.layout
    xattr by default and user defined xattrs
    are prepended with "user."

    osd: flush peering queue (consume maps) prior to boot
    
    If the osd itself is behind on many maps during boot, it will get more and
    (as part of that) flush the peering wq to ensure the pgs consume them.
    However, it is possible for OSD to have latest/recnet maps, but pgs to be
    behind, and to jump directly to boot and join.  The OSD is then laggy and
    unresponsive because the peering wq is way behind.
    
    To avoid this, call consume_map() (kick the peering wq) at the end of
    init and flush it to ensure we are *internally* all caught up before we
    consider joining the cluster.
    
    I'm pretty sure this is the root cause of #3905 and possibly #3995.
