Scenario 1
Start with 3 sg_accels
Take down 2 sg_accels (block until down -- poll port if needed)
Doc adds with uuids (~30 sec for cbgt to reshard)
polling loop: wait for all docs to come back over changes feed
Call validate pindex with correct number of accels
Scenario 2 (Continuation)
When bringing up, you'd have to poll the cbgt_cfg until you get expected number of nodes,
then you could validate the pindex with 2 accels
