Summary:
This is a port of [[ https://github.com/google/leveldb/blob/master/db/fault_injection_test.cc | LevelDB's fault_injection_test ]] to RocksDB. Unfortunately it fails with:
```
==== Test FaultInjectionTest.FaultTest
db/fault_injection_test.cc:491: Corruption: no meta-nextfile entry in descriptor
#0 ./fault_injection_test() [0x41477a] rocksdb::FaultInjectionTest::PartialCompactTestReopenWithFault(rocksdb::FaultInjectionTest::ResetMethod, int, int) /data/users/tomdzk/rocksdb/db/fault_injection_test.cc:491

#5 ./fault_injection_test() [0x408bb8] _start ??:0
```
so I commented out the test invocation in the source code for now (lines 514-520) so it can be merged.
Test Plan: This is a new test.
