------------------------------------

bq. Ideally, stateFormat=1, bootstrapping, predefined cores, legacyCloudMode 
would have all gone away completely in 6x.

+1 to that!  numShards as a System property is evil.

> Deprecate and reduce usage of ClusterState methods which may make calls to ZK 
> via the lazy collection reference

> ClusterState has a bunch of methods such as getSlice and getReplica which 
> internally call getCollectionOrNull that ends up making a call to ZK via the 
> lazy collection reference. Many classes use these methods even though a 
> DocCollection object is available. In such cases, multiple redundant calls to 
> ZooKeeper can happen if the collection is not watched locally. This is 
> especially true for Overseer classes which operate on all collections.
> We should audit all usages of these methods and replace them with calls to 
> appropriate DocCollection methods.
