Review request for lucene.


Repository: lucene


Description
-------

This allows us to add properties to a replica, it takes a collection/slice/replica triplet along with a property.

There is exactly one known "sliceUnique" property at present, preferredLeader. Arbitrary properties can be assigned a "sliceUnique" attribute though.

If sliceUnique==false, then there are no restrictions on how many replicas can have an property/value pair.
