Venkatesh Radhakrishnan	1b114eed4d	Free file iterators for files which are above the iterate upper bound to Improve memory utilization ... Summary: This diff improves the memory utilization for tailing iterators RocksDB, by freeing file iterators which are over the upper bound. It is an updating on Siying's original diff for improving the memory usage for tailing iterators. The changes for the seek and next path are now complete and a test has been added to exercise these paths while deleting file iterators which are above the upper bound.
