Fix 5000 table in one keyspace, to pre_create new tables
Fix 5000 table in one keyspace, to pre_create new tables

Trello: https://trello.com/c/g7WAGkuw

Currently the longevity fails due to timeout when creating the new tables (beyond 5000).
1. Add only 1 table instead of 4 in parallel.
2. Create the table manually before the c-s using driver with bigger timeout.

It'll be good to measure the time it takes to add the new table so we can open issue if it's very long time.
