Grace Law 1851f977c2 Added RocksDB stats GET_HIT_L0 and GET_HIT_L1 
Summary:
  - In statistics.h , added tickers.
  - In version_set.cc,
  -- Added a getter method for hit_file_level_ in the class FilePicker
  -- Added a line in the Get() method in case of a found, increment the corresponding counters based on the level of the file respectively.

Corresponding task: https://our.intern.facebook.com/intern/tasks/?s=506100481&t=5952818
Personal fork: 0c3f2e3600

Test Plan:
In terminal,
```
make -j32 db_test
ROCKSDB_TESTS=L0L1L2AndUpHitCounter ./db_test
```

Or to use debugger,
```
make -j32 db_test
export ROCKSDB_TESTS=L0L1L2AndUpHitCounter
gdb db_test
```
