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.

Test Plan: db_tailing_iter_test.TailingIteratorTrimSeekToNext
