Subject: [PATCH] split RandomizedHarnessTest more ways

Summary:
RandomizedHarnessTest enumerates different combinations of test type, compression type, restart interval, etc. For some combinations it takes very long to finish, causing the test to time out in test infrastructure.
This PR split the test input into smaller trunks in the hope that they will fit in the timeout window. Another possibility is to reduce `num_entries` of course
Closes https://github.com/facebook/rocksdb/pull/3467
