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.
