Summary:
This PR fixes a few cases where RocksDB was not retrying checksum failure/corruption of file reads with the `verify_and_reconstruct_read` IO option. After fixing these cases, we can almost always successfully open the DB and execute reads even if we see transient corruptions, provided the `FileSystem` supports the `verify_and_reconstruct_read` option. The specific cases fixed in this PR are -
1. CURRENT file
2. IDENTITY file
3. OPTIONS file
4. SST footer
Pull Request resolved: https://github.com/facebook/rocksdb/pull/13122
Test Plan: Unit test in `db_io_failure_test.cc` that injects corruption at various stages of DB open and reads
