Thanks for the comments [~appy].

I have asked [~enis] previously about can we run this integration test with unbalanced chaos
monkey:

I don't know whether you are familiar with the different policies that the named chaos monkeys
implement. The test is testing backup RPCs when you kill the servers. The unbalance monkey
is a very specific one that does unbalance + rolling kill all the servers. If you read the
comments for the test, it needs the meta server to not be killed because it assumes that you
are deploying without the meta replicas (I think the test has been developed before the meta
replicas were there).

+ I have changed what you mentioned.
