Description

Using stateFormat=2, our solr always takes a while to start up and spits out this warning line:

WARN - 2014-10-08 17:30:24.290; org.apache.solr.cloud.ZkController; Timed out waiting to see all nodes published as DOWN in our cluster state.

Looking at the code, this is probably because ZkController.publishAndWaitForDownStates is called in ZkController.init, which gets called via ZkContainer.initZookeeper in CoreContainer.load before any of the stateFormat=2 collection watches are set in the CoreContainer.preRegisterInZk call a few lines later.
