[Doc'd + Confirmed] [system test] Replica resident items are heavily evicted. 80 percent active and 20 percent replica resident ratio.

1. create 9 node cluster, each node has 12G RAM, HHD
2. create 2 buckets default and saslbucket, with memory quota 6G and 4G
3. Run the KV use case for 1 day:
loading 50M items to each bucket, make buckets into 80% and 25% resident ratio, access the data 40k ops/sec with 5% create, 5% delete, 5%expire, 5%update, 80% gets for several hours.

Replica resident items are heavily evicted for "default" bucket. 80 percent active and 20 percent replica resident ratio. For saslbucket this is not the case.

Screenshot is attached.
