Add testcase for data being deleted using compaction while having 90% storage utilization

[pehala]

• Create 3 node cluster with rf=3.
• Reaching 90% disk usage.
• Keep it running for an hour, in-between we should clean up some data by dropping tables and keyspace.
• Wait for compaction

reached 91% disk usage and started waiting for 30mins, no write or read.

After 30min idle time, started dropping some tables.

Disk usage drops to about 56%
