Index Namespacing does not work when querying multiple indexes

def add_namespace_to_index(index, cluster) do

When querying multiple indexes (ex: "index_a,index_b,index_c,index_d"), the namespace only adds it for the first instead of all of them.

ex:
Snap.Namespace.add_namespace_to_index("index_a,index_b,index_c,index_d", Snap.Test.Cluster)

Expected: "#{namespace}_index_a,#{namespace}_index_b,#{namespace}_index_c,#{namespace}_index_d"
Actual: "#{namespace}_index_a,index_b,index_c,index_d"

Yep, this looks like a bug. Maybe a nicer API for this would be for these functions to accept a list of indexes which can each be namespaced?

[KoushikDasika]

Yeah that would be awesome. We had to do an ugly hack to work around this.

This should be improved in #188.
