feature(test-cases): Add test cases for low and asymmetric loads

This change adds new configurations for 200gb-48 longevities and one
low load 4 hour longevity, intended to simulate a low load happening
during repair processes, to cover potential overhead like in
scylladb/scylladb#14093.

Task: scylladb/qa-tasks#1416
