Review comment:
I tried. We have 2 options:
1. As you said, we can pass in the factory as a parameter. But we have to
make `HelixZkClientFactory` public. Shall we do this?
`public abstract class HelixZkClientFactory implements
RealmAwareZkClientFactory`
2. It is the implemented as I do. Keep`HelixZkClientFactory` as it is. I
prefer this considering that we don't want HelixZkClientFactory public.
