Summary: BackupableDBTest.RateLimiting test is failing due to timed out on our test server. It might be because of nested loops run sequentially that test different type of combinations of parameters. This patch converts the test into parameterized test so that all combinations can be tested out. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7167 Test Plan: make check -j64 Reviewed By: zhichao-cao Differential Revision: D22709531 Pulled By: akankshamahajan15 fbshipit-source-id: 95518153e87b3b5311a6c1960a191bca58898786
