[HELIX-779] do not clean list field in maintenance rebalancer for new
resources
Setting list fields to empty map will prevent newly added and initially
rebalanced resources during maintenance mode from getting re-balanced after
cluster exists maintenance mode.
The right thing to do is to clear every preference list.
Also added test case to verify
