sdong 806d8916da SimulatedHybridFileSystem to simulate HDD behavior more accurately (#9259) 
Summary:
SimulatedHybridFileSystem now takes a more thorough simualtion of an HDD:
1. cover writes too, not just read
2. Latency and throughput is now simulated as seek + read time, using a rate limiter
This implementation can be modified to simulate full HDD behavior, which is not yet done.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9259

Test Plan: Run db_bench and observe the desired behavior.
