Summary: When using ldb, users cannot turn on force consistency check in most commands, while they cannot use checksonsistnecy with --try_load_options. The change fixes both by: 1. checkconsistency now calls OpenDB() so that it gets all the options loading and sanitized options logic 2. use options.check_consistency_checks = true by default, and add a --disable_consistency_checks to turn it off. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6802 Test Plan: Add a new unit test. Some manual tests with corrupted DBs.

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.
