Manuel Ung aeb4612685 Add counters for seek/next/prev 
Summary:
There are currently no statistics on seeks, only on gets. This adds the following counters:

rocksdb.number.db.seek
rocksdb.number.db.next
rocksdb.number.db.prev
(number of calls)

rocksdb.db.iterate.bytes.read
(number of bytes read from key + value using seek/next/prev)

rocksdb.number.keys.seek.found
rocksdb.number.keys.next.found
rocksdb.number.keys.prev.found
(number of calls where seek/next/prev found a value)

Test Plan:
./db_bench -statistics -benchmarks fillrandom,seekrandom -seek_nexts 5
./db_bench -statistics -benchmarks fillrandom,seekrandom -seek_nexts 5 -reverse_iterator
