Adding advisor Rules and parser scripts with unit tests. (#3934) Summary: This adds some rules in the tools/advisor/advisor/rules.ini (refer this for more information) file and corresponding python parser scripts for parsing the rules file and the rocksdb LOG and OPTIONS files. This is WIP for adding rules depending on ODS. The starting point of the script is the rocksdb/tools/advisor/advisor/rule_parser.py file.

Optimizer's skeleton: use advisor to optimize config options (#4169) Summary: In https://github.com/facebook/rocksdb/pull/3934 we introduced advisor scripts that make suggestions in the config options based on the log file and stats from a run of rocksdb. The optimizer runs the advisor on a benchmark application in a loop and automatically applies the suggested changes until the config options are optimized. This is a work in progress and the patch is the initial skeleton for the optimizer. The sample application that is run in the loop is currently dbbench.
