Description

Currently, if StateModelDefinition already exists in the Znode, even it has already been changed, Helix will not populate the latest version.

It is because in the StateModelDefinition write into ZK function, it only does create operation instead of update.

Fix: 1. Check whether there already exists StateModelDefition.
2. Compare if it is different or not.
