Summary: **Context/Summary:** https://github.com/facebook/rocksdb/pull/13263 temporally disable `track_and_verify_wals=1` with write fault injection in all cases to mitigate a WAL hole not fully debugged. Fully debugging shows the WAL hole only happens under pessimistic TXN when two-phase-commit (2pc) was used. The bug essentially is about 2pc won't be able to discard the corrupted WAL as it would in non-2pc case as part of the WAL write error recovery. So the corrupted WAL will still present in the next DB open and caught by `track_and_verify_wals=1`. This fix is going to take a while. So for now, let's reduce the scope of disabling the testing.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
