Array query parameters

[chriskapp]

Some APIs use array query parameters by using a bracket [] notation, in this example airtable s.

At our SDK we should add support for query arrays, so that a user can provide an actual array and the SDK could add these parameters with []. A problem is, that there are also other array definitions, in this case we use [] but some implementations also simply duplicate the parameters. Maybe we should add also a new keyword to describe the array style.
