REST API: Allows all options for expand_wildcards parameter

This change means that the default settings for expand_wildcards are only applied if the expand_wildcards parameter is not specified rather than being set upfront. It also adds the none and all options to the parameter to allow the user to specify no expansion and expansion to all indexes (equivalent to 'open,closed')

Aggregations: Make the list of buckets for terms and histogram returned as a java.util.List.

The terms and histogram aggregations always have an order. So it would make the
response easier to consume to return the buckets as a list instead of a
collection in order to make it easier to do things like getting the first/last
buckets.
