  1. os/bluestore: set rocksdb iterator bounds for Bluestore::_collection_…

    …list()
    
    When Bluestore::_collection_list() is called during PG removal, rocksdb
    often has to iterate over many rocksdb deletion tombstones from recenently
    deleted onode keys. This change bounds the rocksdb iteration when possible,
    to avoid high latencies caused by iteration over many contiguous deletion
    tombstones.
