anand76 5c19a441c4 Fault injection in db_stress (#6538)
Summary:
This PR implements a fault injection mechanism for injecting errors in reads in db_stress. The FaultInjectionTestFS is used for this purpose. A thread local structure is used to track the errors, so that each db_stress thread can independently enable/disable error injection and verify observed errors against expected errors. This is initially enabled only for Get and MultiGet, but can be extended to iterator as well once its proven stable.

# Using gflags in rocksdb:
# Our project depends on gflags, which requires users to take some extra steps
# before they can compile the whole repository:
# 1. Install gflags. You may download it from here:
# https://gflags.github.io/gflags/ (Mac users can `brew install gflags`)
# 2. Once installed, add the include path for gflags to your CPATH env var and
# the lib path to LIBRARY_PATH. If installed with default settings, the lib
# will be /usr/local/lib and the include path will be /usr/local/include
