Add 'Search Queries' support

[thomas-peyric]

Add support of 'Search Queries' which returns dimension values that match the search specification ( http://druid.io/docs/latest/SearchQuery.html )

@thomas-peyric - I'm working on this at the moment, including a small-ish refactor of the query class. If it's an urgent need, check out https://github.com/liquidm/ruby-druid/tree/search_query. Everything is fully working, including the search queries: query.search(:dim1, :dim2).contains('foo').sort(:strlen).

Yep - it's been implemented (with different syntax) in the ruby-druid team fork.
