Title: CloudSearch - Fix Describe* MalformedInput Error

The following functions all use "member lists":

layer1.describe_domains()
layer1.describe_index_fields()
layer1.describe_rank_expressions()

and as such will give you this when their optional
list specifying one or more individuals is attempted:

Sender
MalformedInput
Unexpected list element termination

They were converted to send FOO.members.N and now
work as expected from the amazon cloudsearch api docs.
