[System Test] Very uneven view compaction across cluster [ranging from 0 to 92% on different nodes.]

1. Setup a 7 Node cluster, with above setup
2. Load items ~ 80M on both the buckets
3. Seeing very uneven view compaction across the nodes for both the buckets.

• View compaction does not kick on some of the nodes, while others behave as expected.
• View Disk size grows enormously on the saslbucket

4. End of the phase, user-triggered compaction is the way to even out the view-disk usage
5. Likewise behaviour for data-compaction as well, it exceeds the 30% threshold level and does not compact across some nodes.

• Seeing this on multiple runs of the same test
