[upr] Rebalance is stuck , fulleviction=true, dgm=60% active

Live cluster.http://172.23.106.235:8091/index.html#sec=servers

• halted the test, and the rebalance stuck cluster above.

Attached collect_info from nodes.

Test to repro:
./testrunner -i /tmp/4-ubuntu12.04-view-simple-3.0.ini -c conf/simple.conf -p get-delays=True,get-cbcollect-info=True,eviction_policy=fullEviction,dgm_run=true,active_resident_threshold=60

Let me know if you need additional information.

The same test, env without dgm, runs ok. But there are currently known rebalance hang issues without dgm as well.

Marking this as critical, although this will block majority of tunable-memory, heavy dgm testing.
